Product Description
Product Overview
The NTC Thermistor (Negative Temperature Coefficient Resistor) is a device whose resistance decreases as ambient temperature increases. It is manufactured by shaping and sintering metal oxides of iron, nickel, cobalt, manganese, or copper at high temperatures. This thermistor is designed for applications requiring temperature-dependent resistance.
