NTC Thermistors are thermistors which use a negative temperature coefficient (NTC) of resistance. This means as the temperature increases, the resistance decreases. When applied appropriately, these thermistors can be used to measure temperature in many different applications, and in this article we discuss the application field and working principle of the 120-602FAF-Q02.

Types of NTC Thermistors

NTC thermistors, such as the 120-602FAF-Q02, are usually composed of a semiconductor-grade ceramic material that is sintered with metal oxides to form the sensor. This ceramic material contains primarily nickel and cobalt, although other metals may be used to vary the characteristics of the thermistor. Depending on the application, the overall shape of the thermistor can differ significantly, from thin film thermistors to radial leaded devices.

120-602FAF-Q02 Application Field and Working Principle

The 120-602FAF-Q02, a radial leaded NTC thermistor, is specifically designed for measurement and control applications. It is typically used as the activator for temperature sensitive relays, temperature switches, or as the sensing element in temperature control circuits, thermally triggered surge protectors, etc.

The working principle of the 120-602FAF-Q02 is based on the NTC thermistor model. As temperature increases, the resistance of the thermistor decreases. This resistance can be measured using an appropriate circuit, such as a voltage divider or Wheatstone bridge, and the corresponding temperature can be calculated. Since the resistance is a function of temperature, the thermistor can be used in a wide range of temperature measuring applications.

Advantages of NTC Thermistors

One of the major advantages of using NTC thermistors, such as the 120-602FAF-Q02, is that they offer excellent accuracy and long-term stability. These thermistors are also cost effective due to their ease of manufacturing, small size, and low power requirements. Additionally, these thermistors are safe and reliable, as they are insensitive to outside environmental influences, such as humidity, and have low drift over time. Finally, these thermistors can be used over a wide temperature range with excellent linearity, making them suitable for a wide range of temperature measurement applications.

Conclusion

NTC thermistors, such as the 120-602FAF-Q02, have a wide range of applications in the temperature measuring field. With their superior accuracy and long-term stability, these thermistors can be used to measure temperature in many different environments. Additionally, these thermistors are cost effective, reliable, and perform well over a wide temperature range.
