Product Description
Product Overview
The NTC Thermistor is a Negative Temperature Coefficient Resistor designed to reduce resistance as ambient temperature increases. It is constructed from 2 or 4 types of metal oxides (iron, nickel, cobalt, manganese, or copper) that are shaped and sintered at high temperatures. This specific model, 206RV179 NTC 3D-15, features a nominal resistance of 3, a chip diameter of 15mm, and an inward-bent lead design with black coating.
Product Attributes
- Brand: NTC
- Material (Wrapper): Phenolic aldehyde
- Material (Down-lead): Tinned Electron Wire
- Color (Coating): Black
