Product Description

Product Overview

The NTC Thermistor is a Negative Temperature Coefficient Resistor designed to decrease in resistance as ambient temperature increases. It is manufactured from 2 or 4 types of metal oxides (iron, nickel, cobalt, manganese, copper) that are shaped and sintered at high temperatures. This specific model, 206RV176 NTC 5D-5, features a nominal resistance of 5 and a chip diameter of 5mm.
