Product Description
NTC Thermistor 206RV197 NTC 5D-11
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 has a nominal resistance of 5, a chip diameter of 11mm, and a pitch of 7.5mm, with black coating and straight leads.
Product Attributes
- Wrapper Material: Phenolic aldehyde
- Down-lead: Tinned Electron Wire
- Coating Color: Black
