NTC thermistors are temperature sensors used to measure the temperature of various environments. The DC95Y103ZN is one type of NTC thermistor that is finding increasing usage in a variety of sectors due to its accuracy and affordability. In this article, we’ll take a closer look at the application field and working principle of the DC95Y103ZN.

Application Field

The DC95Y103ZN is a 25 kΩ thermistor and is often used in automotive applications, particularly to measure engine temperature and air intake temperature. It is also used to monitor circuit board temperature. The NTC thermistor provides an affordable and effective means of monitoring operating temperatures in motor and generator assemblies, steam turbines, and other industrial machinery.

The DC95Y103ZN is also increasingly used in consumer electronics such as set-top boxes and digital TVs to monitor the occasional surges in temperature and to ensure adequate cooling arrangements are in place. Additionally, its high accuracy – right up to 0.1 ºC – makes it an attractive choice for household appliances and devices that require precise temperature monitoring.

Working Principle

The DC95Y103ZN NTC thermistor works using the thermistor effect, which is the property of certain materials, such as certain types of ceramic, that have a negative temperature coefficient of resistance. Simply put, when the temperature of such materials increases, their resistivity decreases.

In the case of the DC95Y103ZN, the thermistor has a resistance value of 25kΩ at 25ºC. However, the resistance decreases as the temperature rises, and vice versa. As such, the thermistor provides an easy way to measure temperature since the resistance can be measured and calibrated to determine the exact temperature.

The DC95Y103ZN is designed for use in online monitoring applications, which means it is connected to a circuit board all the time. This means that the changes in resistance can be read in real time to monitor the temperature. The type of circuit that is used to measure the resistance will depend on the application. A four-wire circuit is preferred in high-precision applications as it minimizes errors caused by lead resistance.

Overall, the DC95Y103ZN is an effective and accurate NTC thermistor that is suitable for a wide range of applications, from automotive and industrial to consumer and home electronics. It is a reliable and affordable choice for temperature monitoring.
