Glass-sealed thermistor refers to a thermistor sealed with insulating glass. Because the glass is insulated, the thermistor is not affected by the additional temperature, which greatly improves the sensitivity and accuracy of the control. The appearance of the glass-sealed thermistor is as follows:



Glass package thermistor:
The thermistor packaged in glass has a thermal chip inside. Its main features are small size, high precision, fast response and anti-aging. Due to the characteristics of the glass package, it is suitable for use in harsh environments such as high temperature and humidity. This thermistor generally has a single-ended glass seal and an axial lead. This thermistor is very common, and it is widely used in office automation equipment, temperature detection and temperature control of various household appliances, etc.

Glass thermistor is a miniature resistance device made by using the thermal characteristics of certain't-conductor glass.
The more commonly used ones are VaUa-PZC)5-13af) series. CuCI-;3zfl; ,-C`aU series and Mn(7IzUa-S;D) series, etc. The conductivity of this glass is due to the transition metal ions having two different valence states and the result of the transition process. Usually a p-type semiconductor. The resistivity is between 1U-1}}}1-two. The carrier density is lfl}}.}cm3._The mobility is generally fn-in-'-cm}[V"s)-the melting temperature of the oxide glass semiconductor varies with the composition. ,1i has f)5, WL)3, etc. When the content increases, the melting temperature increases, generally b50 to 1100 C, and the annealing temperature is 200 to 300 C'., The vortex enhancement can be made of ceramic or quartz. The use is similar to semiconductor glass. It can be used to make devices or parts of electronic computers, anti-radiation missiles, spacecraft and atomic energy reactors, and can also be used to make electronic circuit temperature compensation sensitive components, infrared detectors, etc.
