Temperature sensors are devices used to measure the temperature of a physical body by contact with it. There are several types of temperature sensors, such as thermocouples, infrared sensors, RTDs (resistance temperature detectors), and NTC thermistors. This article is focused on NTC thermistors and the NTC 0805J15K in particular.

What are NTC thermistors ?

NTC (negatively-temperature-co-efficient) thermistors are temperature-sensitive semiconductors which have a negative temperature coefficient of resistance. In other words, as the temperature increases, the resistance decreases. NTC thermistors are made from a combination of oxides, metals, and other materials which, when mixed together, create a material with temperature dependent characteristics. Due to their low cost and acceptable accuracy, these thermistors are commonly used in many temperature sensing applications.

NTC 0805J15K Application field and Working Principle

The NTC 0805J15K is a type of NTC thermistor that is specifically designed for surface mount applications. The 0805J15K is manufactured as a 0805 (2035 mil) surface-mount chip with pin spacing, making it one of the smallest thermistors. This thermistor has a 93.75 ohm negative temperature coefficient of resistance (NTR) at 25 °C, making it useful in many applications that require temperature sensing such as atmospheric, environmental, and industrial systems.

The NTC 0805J15K thermistor works by sensing changes in temperature and responding by changing its resistance. A decrease in temperature causes an increase in the thermistor’s resistance, while an increase in temperature causes a decrease in the thermistor’s resistance. This helps to ensure accurate temperature sensing and control in any application using the 0805J15K.

This thermistor is also designed to operate in high temperature and demanding conditions. It is RoHS compliant, shockproof, and can withstand up to 125 °C without any significant loss of accuracy. Additionally, the NTC 0805J15K has a fast response time that enables it to accurately measure temperatures with an acceptable accuracy range of 0.2 °C.

The NTC 0805J15K can be used in a variety of temperature sensing applications. It is often used in automotive climate control systems, HVAC systems, medical devices, building automation systems, and industrial equipment.

The 0805J15K is a popular choice for many applications because of its small size and low cost. Additionally, its fast response time ensures that it can accurately measure temperatures with an acceptable accuracy range of 0.2 °C. Lastly, its ability to operate in high temperature and demanding conditions makes it an ideal choice for a variety of temperature sensing applications.
