Product Description

Product Overview

NTC Thermistor is a Negative Temperature Coefficient Resistor whose resistance changes with ambient temperature changes. Thermistor comprises 2 or 4 kinds of metal oxides of iron, nickel, cobalt, manganese and copper, being shaped and sintered at high temperature. This NTC thermistor (Model: 206RV185 NTC 2.5D-11) features a nominal resistance of 2.5, a chip diameter of 11mm, and a pitch of 7.5mm, with black inward-bent leads.
