Vishay / BC Components NTCLE350E4 Insulated Lead NTC Thermistors are high-temperature sensors with low thermal gradient PEEK insulated NiFe leads suited for automotive and industrial applications that require withstanding to +185°C. The negative temperature coefficient thermistors consist of a mini-chip soldered between two 32AWG PEEK insulated silver-plated NiFe alloy leads which provide low thermal conductivity. The thermistors are then coated with black colored epoxy lacquer. High adhesive strength between the PEEK wires and encapsulating lacquer improves the behavior of the components in high humidity conditions (+85°C/85% relative humidity). The sensor’s comprehensive robust construction also makes it suitable for challenging assembly mounting processes including welding, brazing, molding, and potting.
When the component measures a hot spot inside an application, practically no thermal loss will occur through the wires. The NTCLE350 components won’t present any temperature deviation and will sense an exact real nominal temperature within ±1.7°C at a peak temperature of +185°C.
With AEC-Q200 qualification, the NTCLE350E4 components can be used for classical motor thermal sensing applications or HVAC, oil temperature sensor (OTS), and exhaust gas recirculation (EGR) applications. The Vishay / BC Components NTCLE350E4 Insulated Lead NTC Thermistors are not intended for fluid immersed applications or for continuous contact with water or conducting liquids.
