Product Description
Product Overview
The NTC Thermistor is a Negative Temperature Coefficient Resistor designed to decrease its 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 thermistor is suitable for applications requiring temperature-dependent resistance, operating within a range of -40 to +200.
Product Attributes
- Wrapper Material: Phenolic aldehyde
- Lead Wire: Tinned Electron Wire
- Coating Color: Black
