Product Description

Product Overview

The NTC 22D-11 is a Negative Temperature Coefficient (NTC) thermistor. Its resistance decreases as ambient temperature increases. This thermistor is manufactured from 2 or 4 types of metal oxides (iron, nickel, cobalt, manganese, or copper) which are shaped and sintered at high temperatures. It features a black coating and inward-bent leads.
