　　Electronic components are the building blocks of modern technology. They power everything from smartphones and computers to cars and airplanes. However, finding the right electronic components can be a challenging and time-consuming task, even for seasoned veterans at electronics OEMs and EMSes. In this blog post, we will discuss the basics of how to find electronic components and provide some strategies for locating the parts you need.

What are the procurement channels of electronic components

　　One of the best ways to find electronic components is by using online search engines and marketplaces. These platforms can help you quickly locate parts from a variety of manufacturers and suppliers. We will discuss some of the most popular electronic component search engines and marketplaces, and provide tips for using them effectively.

　　In addition to online resources, there are other strategies you can use to find electronic components. These include understanding electronic component specifications, using cross-reference tools, and finding alternative or equivalent parts.

　　What are the procurement channels of electronic components

　　When it comes to finding electronic components, there are several broad options available.

　　The first and most popular method is to search online marketplaces and distributors. These platforms offer a wide selection of parts from various manufacturers and suppliers, making it easy to find the parts you need. Some of the most well-known online marketplaces and distributors include AMEYA360. Most electronic manufacturers choose one or two distributors and build trusted relationships with them, going back time and time again for supply.

　　Ameya Holding Limited was established in Hong Kong in 2007 and later in 2011, Shanghai Huanghua Information Technology Co., Ltd. was registered, marking the launch of our online platform, AMEYA360 (www.ameya360.com), providing a one-stop solution for electronic component procurement.

　　At present, Ameya Holding Limited has secured authorized agency agreements with over 80 renowned original manufacturers, including ROHM, Murata, Panasonic, Taiyo Yuden, Susumu, Rubycon, Renesas (IDH), NXP (IDH), 3Peak, GigaDevice, Novosense, Dioo, and others. They also distribute brands like TI, ADI, ST, Infineon, and Microchip. With a vast network of more than 3,500 high-quality suppliers, AMEYA360 Mall offers an impressive selection of over 8 million types of products available for ordering, with over 5 million components in stock.

　　Another option is to use electronic component search engines. These search engines allow you to enter the part number or specifications of the component you need and provide a list of results from multiple sources. Some of the most popular electronic component search engines include Octopart, Findchips, and TrustedParts.

　　Larger buyers will often have the option to purchase electronic components directly from manufacturers. This can be a more cost-effective and reliable option for buyers who require large quantities of components or need custom parts that are not readily available through other sources. To purchase components directly from manufacturers, buyers typically need to have a strong relationship with the manufacturer and meet certain minimum order requirements.

　　If you are having trouble finding a particular part or need help with procurement, you may want to consider using an electronic component broker. These brokers specialize in sourcing hard-to-find or obsolete parts and can often provide faster and more reliable access to these components than other sources. There’s a huge diversity of brokers in the secondary market, and they can be difficult to trust – but sometimes, they’re the only ones with inventory available.

　　The best electronic component search engines

　　When using electronic component search engines, it's important to compare results across multiple sources and verify the authenticity and quality of the components you are purchasing. They’re plugged into a much wider section of the market than the authorized distributors, but that sometimes comes at the cost of less accurate data. Top search engines include:

　　Octopart: Octopart is a popular electronic component search engine that provides real-time information on pricing, availability, and technical specifications from a variety of manufacturers and distributors. Octopart has a user-friendly interface and powerful search features that allow you to filter results by a range of criteria, including price, quantity, and lead time.

　　Findchips: Findchips is another top electronic component search engine that offers a comprehensive database of parts from a wide range of suppliers. It provides detailed information on pricing, availability, and technical specifications for each part, and allows you to compare prices and availability across multiple sources.

　　Trustedparts: On the other hand, Trustedparts focuses on hard-to-find and obsolete parts. It provides access to parts from a wide range of suppliers and allows you to search by part number, manufacturer, or keyword. The site also includes tools for cross-referencing and part substitution to help you find alternative components when needed.

Application of different types of electronic components in circuit design

　　Electronic components are the building blocks of any electronic circuit. They are the fundamental units that are used to create and manipulate electric signals, and they can be combined in various ways to create a wide range of circuits with different functions.In this article, AMEYA360 Chip purchasing network will provide an overview of the different types of electronic components and their applications in circuit design.　　Topics covered:　　Passive components (including resistors, capacitors, and inductors)　　Active components (including transistors, diodes, and operational amplifiers)　　Electromechanical components (including motors, switches, and relays)　　There are three main categories of electronic components: passive components, active components, and electromechanical components.　　Passive components are the simplest type of electronic component. They do not have the ability to amplify or generate an electric current, and they rely on the flow of current from an external source to perform their function. Examples of passive components include resistors, capacitors, and inductors.　　Resistors are one of the most common passive components, and they are used to control the flow of electric current in a circuit. They are typically represented by a set of colored bands on their body, and the colors indicate the resistance value of the resistor. The resistance of a resistor is measured in ohms, and it determines how much the flow of current will be hindered by the resistor.　　Capacitors are another type of passive component, and they are used to store electric charge in a circuit. They are commonly used to smooth out fluctuations in the flow of current, and they can also be used to filter out certain frequencies in a signal. Capacitors are typically made up of two metal plates separated by a dielectric material, and the capacitance of a capacitor is measured in farads.　　Inductors are passive components that are used to store energy in a magnetic field. They are commonly used in circuits to filter out high-frequency signals, and they are also used in power supplies to filter out unwanted noise. Inductors are typically made up of a coil of wire, and the inductance of an inductor is measured in henries.　　Active components, on the other hand, are electronic components that have the ability to amplify or generate an electric current. Examples of active components include transistors, diodes, and operational amplifiers.　　Transistors are active components that are commonly used as switches or amplifiers in circuits.

Knowledge of electronic components: How Do Thermistors Work?

　　A thermistor is a type of temperature sensor made from semiconductor materials. The word "thermistors" is a combination of "thermal" and "resistor," which helps give a clue to its function- to change its electrical resistance in response to changes in temperature.　　Understanding Thermistors　　Thermistors are used in various applications requiring temperature measurements, such as in thermostats, controllers, and temperature-compensating circuits. They are particularly useful in tools requiring high accuracy and fast response times. A thermistor is a temperature sensor that uses the change in resistance with temperature to measure temperature. It is commonly used in electronic circuits to monitor temperature and control heating and cooling systems.　　Importance of Understanding How Thermistors Work　　Understanding how thermistors work is essential since it enables accurate temperature measurements, a critical activity in many applications such as electronic circuitry, medical equipment, and environmental monitoring. It also allows for properly selecting and using thermistors in various systems and devices.　　The Physics Behind Thermistors　　Electrical resistance is a material's opposition to the flow of electric current. It is measured in ohms (Ω). The temperature coefficient of resistance (TCR) describes the relationship between temperature and electrical resistance, which measures how much resistance changes with temperature. There are two types of thermistors: negative temperature coefficient (NTC) and positive temperature coefficient (PTC). NTC thermistors have a negative TCR, which means their resistance decreases as temperature increases. PTC thermistors have a positive TCR, which means their resistance increases as temperature increases.　　How Are Thermistors Constructed?　　Thermistors are typically made of metal oxides, such as manganese, nickel, cobalt, or copper, which exhibit a significant change in resistance with temperature. The manufacturing process involves mixing the metal oxide with a binder and pressing the mixture into a desired shape. The mixture is fired at high temperatures to remove the binder and sinter the metal oxide particles. The resulting thermistor can vary in size and shape but is typically small and cylindrical, with a few millimeters or less diameter.　　How Thermistors Work in Practice　　Thermistors work by changing their resistance in response to changes in temperature. They are often used in circuits to measure temperature, as their resistance can be easily converted into a temperature reading. Thermistors are connected in series with a fixed resistor and a voltage source to create a voltage divider circuit. The voltage across the thermistor is then measured and used to calculate the temperature. The thermistor's resistance decreases as the temperature increases, causing the voltage across it. This change in voltage is proportional to the change in temperature.　　Advantages and Limitations of Thermistors　　The advantages of thermistors include their high sensitivity, fast response time, and low cost. They are also relatively small and can be used in several applications. However, thermistors have limitations, such as non-linear response, self-heating, and a limited temperature range. Compared to other temperature sensors, such as RTDs or thermocouples, thermistors are less accurate but more cost-effective for many applications. They are commonly used in consumer electronics, HVAC systems, and automotive applications.　　Final Words　　Understanding thermistors is crucial for many industries that rely on temperature control and measurement. The ability of thermistors to provide highly accurate and sensitive readings makes them an essential component in various applications, including medical devices, automotive engines, and electronic devices. Engineers and technicians can design and optimize systems for better performance and efficiency by knowing how thermistors work. Therefore, a thorough understanding of thermistors is vital for anyone working in fields that require temperature monitoring or control.　　Visit ww.ameya360.com to learn more about thermistors and other electronic components and get customized ones.
