NTC thermistors are temperature sensors that exhibit a decrease in electrical resistance when subjected to an increase in temperature. The SB302J1K is a chip-type thermistor that combines metal film elements with a negative temperature coefficient (NTC) thermistor element, achieving a highly precise temperature sensing performance with a wide temperature-measuring range and fast response speed. It is widely used for temperature measurement in a wide variety of applications.

The SB302J1K is a two-terminal NTC thermistor with a very low resistance, high sensitivity, and high accuracy, which is well-suited for applications with a wide temperature range. This chip type thermistor has a two-terminal design that allows it to be easily integrated into circuits while providing efficient current flow. The sensor elements are encapsulated in a metal film body and can be mounted on a printed circuit board. The enclosure allows it to provide a temperature sensing performance over a wide operating temperature range from -40°C to +125°C.

The working principle of the SB302J1K is based on the NTC thermistor element embedded in the thermistor body. It consists of two layers: a ceramic body and a metal film. The ceramic layer of the thermistor body acts as a substrate to house the metal-film, which is configured to make a resistance element. When the temperature changes, the resistance of the NTC element changes, thus providing a voltage output that can be measured and interpreted as temperature.

This chip type thermistor has a wide range of applications, including temperature sensing in automotive, medical, industrial, and consumer electronics. It can be used in automotive cooling systems to measure the temperature of the engine coolant and in consumer electronics to measure the temperature of the processor. It can also be used for temperature measurements in HVAC systems, medical equipment, food processing equipment, and other industrial applications. The sensor is also used in high-precision temperature measurement applications such as oven temperature control, machine tool control, and medical thermometry.

The SB302J1K is an ideal choice for applications requiring high-precision temperature sensing with a wide operating temperature range and fast response time. It provides a low-cost, efficient solution for a wide range of applications and is designed to withstand extreme temperatures and harsh environmental conditions. This chip type of thermistor is constructed with a metal film and ceramic body, allowing it to provide a highly accurate temperature sensing performance with a wide temperature range and fast response time.
