- Parameters
1. Product Description
The MF51 glass encapsulated NTC thermistor is a product formed by connecting the Dummy wire lead and
the chip electrode on each of the two electrode surfaces of a high-precision NTC thermistor chip through sintered silver paste, and then covering each with a glass tube under high-temperature melting. It can be widely used in air conditioning, heating equipment, electronic thermometers, liquid level sensors, automotiveelectronics and so on.
2. Product Features
l Small size, fast thermal induction speed, and hightesting accuracy;
l Glass packaging, resistant to high temperature andhumidity in harsh environments
l Good consistency and interchangeability;
l Wide working temperaturerange, -50℃~250℃.
