Product Description

Product Overview

The NTC Thermistor (Negative Temperature Coefficient Resistor) is a component whose resistance decreases as ambient temperature increases. It is manufactured from 2 or 4 types of metal oxides (iron, nickel, cobalt, manganese, or copper) shaped and sintered at high temperatures. This specific model, 206RV191 NTC 3D-13, features a nominal resistance of 3, a chip diameter of 13mm, and is coated in black with inward-bent leads.
