Glass Bead Thermistor, Single-ended Glass-sealed Thermistor

As one of the leading industrial sensor suppliers, TOPOS was founded in 2003. In the beginning, it is the first company that can mass-produce the most stable glass-bead type thermistors. Ten years sharpening a sword, TOPOS becoming the high-tech company in this field. Our main products are NTC chips, NTC type thermistors (negative thermistors), Temperature sensors, Humidity/Gas sensors, widely applied in the green-car industry, smart home appliances, electronic thermometer, ... etc.

Note: What is the B value:
A material constant that describes the resistance-temperature relationship. The value of B can reflect the scale of resistance to temperature change between two specific temperatures. As the temperature changes, the resistance value of a product with a large B value under the same conditions changes more, that is to say, it is more sensitive.
