Product Description

Product Overview

The NTC 206RV159 NTC 5D-11 is a Negative Temperature Coefficient (NTC) thermistor. Its resistance decreases as the ambient temperature increases. This thermistor is manufactured using 2 or 4 types of metal oxides (iron, nickel, cobalt, manganese, copper) shaped and sintered at high temperatures. It features a black coating and inward bent leads.
