R25 Surface Mount Temp Sensor
R25 10kΩ B25 / 85 3435K Battery Terminal NTC Temperature Sensor For EV Battery
Brief Introduction:
The item is a temperature sensor for EV Electric Battery. Typical applications include battery control systems in EV cars. EV battery temperature sensor consists of an NTC chip thermistor mounted in an Aluminum probe (AL Probe), with insulated flexible wire (XLPE insulated wire UL4411 125℃ & UL4413 150℃)and terminals. One standard resistance value and beta value: R25℃= 10kΩ and B25/85=3435k.
