Product Description
Product Overview
The NTC Thermistor is a Negative Temperature Coefficient Resistor designed to decrease resistance as ambient temperature increases. Constructed from a blend of metal oxides (iron, nickel, cobalt, manganese, or copper) shaped and sintered at high temperatures, this thermistor offers reliable performance across a wide operating temperature range. It is suitable for applications requiring precise temperature sensing and control.
