Product Description
Product Overview
The NTC Thermistor is a Negative Temperature Coefficient Resistor designed to decrease its resistance as ambient temperature increases. It is constructed from 2 or 4 types of metal oxides (iron, nickel, cobalt, manganese, or copper) that are shaped and sintered at high temperatures. This type is specifically the 206RV183 NTC 8D-15 model, featuring a nominal resistance of 8 and a chip diameter of 15mm.
