Product Description
Product Overview
The NTC Thermistor is a Negative Temperature Coefficient Resistor designed to decrease its resistance as ambient temperature increases. It is manufactured from a combination of 2 or 4 metal oxides, including iron, nickel, cobalt, manganese, and copper, which are shaped and sintered at high temperatures. This thermistor is suitable for applications requiring temperature-sensitive resistance characteristics.
