The self-developed ceramic film glass package thermistor uses ceramic film and glass to encapsulate the NTC resistor chip. The mechanical strength of the ceramic sheet is much higher than that of glass. Therefore, when the two electrode leads are broken during the installation and use of the product, The glass bulb will not be easily damaged, the product has good sealing performance, and the production qualification rate and reliability are guaranteed. In addition, the production cost of the ceramic sheet is low. While slightly increasing the production cost of the product, it significantly improves the mechanical strength and reliability of the product, and can ensure that the product has all the advantages of fast response speed, high temperature resistance, humidity resistance, and good stability of conventional glass-sealed resistors.
