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 206RV173 NTC 1.5D-15) has an impedance of 1.5, a chip diameter of 15mm, and a pitch of 7.5mm, featuring black coating and inwardly bent leads.
Product Attributes
- Wrapper Material: Phenolic aldehyde
- Down-lead Material: Tinned Electron Wire
- Coating Color: Black
