NTC thermistors are a type of temperature sensing device used in a variety of applications to measure and control temperature. B57620C681M62 is one particular type of NTC thermistor often used in precision electronic applications as a thermally sensitive temperature sensing device. This article will discuss the application fields and working principles of B57620C681M62 NTC thermistors.

Application fields

B57620C681M62 NTC thermistors are primarily used as temperature sensors in highly precise electrical applications. They are often found in computers, consumer electronic products, and even medical equipment. Additionally, they are used for over-temperature protection applications. In these applications, B57620C681M62 thermistors are often inserted between two conductors to act as a thermal switch should the temperature reach a certain threshold. This prevents dangerous thermal runaway and increases the safety of an application.

B57620C681M62 thermistors are also used in high accuracy sensors for monitoring temperature in high accuracy workplaces such as laboratories or other demanding environments. These thermistors are able to provide highly accurate measurements and are available in a wide range of band gap values and resistance values, making them suitable for most types of temperature sensing applications.

Working Principle

NTC thermistors such as B57620C681M62 are temperature sensing devices which operate on a phenomenon known as “negative temperature coefficient” (NTC). This refers to the effect of temperature on electrical resistance. As the temperature increases the resistance of the thermistor decreases, and vice versa. This change in resistance provides an accurate indication of the temperature, enabling it to be measured.

B57620C681M62 NTC thermistors also operate using the self-heating effect. This is when the thermistor dissipates electrical energy in the form of heat, which in turn increases its temperature. This phenomenon is particularly useful in applications which measure very low temperatures, as the device will continue to generate heat until it reaches a certain threshold before the resistance will begin to decrease.

Conclusion

The B57620C681M62 NTC thermistor is an important temperature sensing device used in a variety of highly precise applications. It functions on the principle of NTC – the effect of temperature on resistance – and the self-heating effect, making it highly accurate and suitable for a range of temperature sensing applications. It is often used in computers, consumer electronics, medical equipment and various other applications.
