NTC thermistors are temperature-sensitive semiconductor devices that provide accurate and reliable temperature readings across a wide range of temperatures. The BR42KB503M is a NTC thermistor developed by the Japanese company Kyoto Semiconductor Co. Ltd. It offers precise temperature monitoring in a wide range of applications and is suitable for use in industrial and consumer electronic products. The BR42KB503M is a highly accurate NTC thermistor that offers a wide temperature range from -40 to +225°C. Its narrow sensing range of just 3.4°C offers maximum accuracy in areas with extreme temperature changes.

The BR42KB503M thermistor is a small, lightweight device with a compact size for easy and flexible installation and mounting. The thermistor has a higher sensitivity than other standard thermistors, with a sensitivity of 0.8V/°C and a saturation voltage at 10 ohms. This makes it particularly suitable for applications requiring fast and accurate measurements. It also features a reverse temperature coefficient of thermistor resistance (RTCR), meaning that its resistance increases as temperature decreases, and decreases as temperature rises. This characteristic provides the thermistor with a robust temperature-sensing mechanism.

The BR42KB503M thermistor’s wide temperature range makes it suitable for a variety of applications including thermal sensing in motors, power supplies, heaters, liquid level controllers, automotive engine control systems and much more. It is also suitable for applications that require accurate temperature measurement over a wide temperature range such as building climate control systems, refrigerator temperature sensors, temperature monitoring for food packaging and processing, heating and cooling systems, etc.

In addition to its wide temperature range, the BR42KB503M thermistor also features a fast response time, good stability, and high repeatability. This thermistor can accurately sense temperature changes in milliseconds, and is able to detect small fluctuations in temperature accurately and quickly. It also helps to minimize errors in temperature measurements due to its high repeatability. The thermistor has a low-resistance strain gage design, which allows for accurate measurement of temperatures up to 500°C.

The working principle of the BR42KB503M thermistor is based on the basic principle of thermodynamics. The thermistor is composed of a ceramic material with a certain doping rate and an induced electric field. When the temperature changes, the electric field affects the resistance of the thermistor, causing the thermistor’s resistance to rise or decrease as temperatures drop or rise, respectively. The rate of change in the thermistor’s resistance depends on the doping rate and the induced electric field.

Overall, the BR42KB503M is a reliable and accurate NTC thermistor designed for use across a wide range of temperature applications. It offers features such as a wide temperature range, fast response time, good stability, and high repeatability. These features make it a suitable choice for applications requiring precise temperature monitoring.
