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.

Electronic Components Purchasing：14 Essential Electronic Components and their Functions

　　According to AMEYA360 The world of electronic components can be summarized with a short list of items. Here are more details on these essential parts of modern electronics.　　What are the electronic components? The following components are among the most common found in electronic devices:　　Microcontroller　　Transformer　　Battery　　Fuse　　Relays　　Switches　　Motors　　Circuit Breakers　　What are electronic components used for? Microcomputers are small computers used to control a multitude of devices, such as power tools, remote controls, medical equipment and office machines. Batteries convert chemical energy to electrical energy. The two different cells of a battery are anode (+) and cathode (-).　　Fuses help preserve components from overloading with excessive current. A fuse consists of connection body, support, contacts and metal-fuse material such as Zinc or copper. As a protective device, a circuit breaker can be controlled with a remote switch. It is designed to protect the circuit from overloading or a short circuit.　　Switches interrupt current. The four types of switches are: single pole single throw (SPST), single pole double throw (SPDT), double pole single throw (DPST) and double pole double throw (DPDT).　　Relays are electromechanical switches that shut power on or off. A relay includes an electromagnet, an armature, a series of electrical contacts, and a spring.　　Motors convert electrical energy into mechanical energy. Key components include a rotor, stator, bearings, conduit box, enclosure, and eye bolt. From watches, to home entertainment equipment, to vehicles; motors can power a wide array of devices.　　What are active and passive components in electronics? Active components include transistors, while passive components include transformers, inductors, resistors, capacitors. Transformers are commonly used to step up or step down power. A resistor restricts current flow. It is used in thermistors and potentiometers. Similar to a low capacity battery, a capacitor allows delays to occur in circuits. Inductors are used to control frequencies.　　When building electronic circuits, you will work with a number of basic electronic components, including resistors, capacitors, diodes, transistors, inductors and integrated circuits. Below is a brief overview of the components and their functions.　　Resistors: A resistor is one of the components you will come across in an integrated circuit. Like the name suggests, the device resists the flow of current. Resistors are graded based on their power ratings (amount of power they can handle without exploding) and resistance values (capacity to resist current). The measurement is done in units know as ohms. The electronic symbol of the unit is O.　　Capacitors: These components can store electric charge temporarily. The components come in different varieties, with the most common ones being electrolytic and ceramic disk. The capacity of a component is usually measured in microfarads (µF).　　Diodes: Diodes allow electric current to flow in a single direction only. Each diode has two terminals known as the anode and cathode. When the anode is charged with positive voltage and the cathode with a negative one, electric current can flow. Reversing these voltages will prevent the current from flowing.　　Transistors: These components are easy to identify through their three terminals. For the components to work, voltage has to be applied to one of them; the base terminal. The base can then control current flow in the two other terminals (the emitter and collector).　　Inductors: These are passive components that store energy in form of a magnetic field. An inductor simply consists of a coil of wire wound around some kind of core. The core could be a magnet or air. When current passes through the inductor, a magnetic field is created around it. The magnetic field is stronger if a magnet is used as the core.　　Integrated Circuits: An integrated circuit refers to a special device that has all the components required in an electronic circuit. The component has diodes, transistors, and other devices, all of which are etched on a tiny piece of silicon. The components are used in many electronic devices, including watches and computers.　　Microcontrollers: Microcontrollers are small computers used to control a multitude of devices, such as power tools, remote controls, medical equipment and office machines.　　Transformers: Built with two coils of wire, transformers are commonly used to step up or step down power.　　Batteries: Batteries convert chemical energy to electrical energy. The two different cells of a battery are anode (+) and cathode (-).　　Fuses: Fuses help preserve components from overloading with excessive current. A fuse consists of connection body, support, contacts, and metal-fuse material such as zinc or copper.　　Relays: These electromechanical switches shut power on or off. A relay includes an electromagnet, an armature, a series of electrical contacts and a spring.　　Switches: Switches interrupt current. The four types of switches are: single pole single throw (SPST), single pole double throw (SPDT), double pole single throw (DPST), and double pole double throw (DPDT).　　Motors: Motors convert electrical energy into mechanical energy. Key components include a rotor, stator, bearings, conduit box, enclosure, and eye bolt.　　Circuit Breakers: As a protective device, a circuit breaker can be controlled with a remote switch. It is designed to protect the circuit from overloading or a short circuit.
