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.
