Temperature Sensors - NTC Thermistors
B57864S0282H040 is a thermistor that is designed to sense temperatures. It is classified as a Negative Temperature Coefficient (NTC) thermistor, meaning that when temperatures increase, the resistance of the thermistor decreases.
Application Field
The B57864S0282H040 is used in many different applications. It is commonly used in over-current, over-voltage, and over-temperature protection in consumer electronics, HVAC systems, thermostats, as well as industrial and medical applications. It also used in temperature measurement for laboratories and security systems. Additionally, it is used in temperature compensation for various applications.
Working Principle
The B57864S0282H040 is an NTC thermistor, meaning that it has a non-linear resistance-temperature characteristic with a negative temperature coefficient. The thermistor is made of a sintered material, which is a special ceramic material with metal oxide particles. The thermistor works by providing a variable resistance based on the temperature the ceramic material is exposed to. The resistance decreases as the temperature increases.
When the temperature increases, the metal oxide particles within the thermal sensitive ceramic material create an interaction that generates a current flow. This current flow is used to measure the temperature. The thermistor is designed with a specific resistance-temperature coefficient so it can accurately measure temperatures within a given range.
Conclusion
The B57864S0282H040 thermistor is an NTC thermistor designed for sensing and measuring temperatures in a variety of applications. It is made of a special thermal sensitive ceramic material with metal oxide particles that generate a current flow when temperatures increase. The thermistor is designed to accurately measure temperatures within its given range.
