This NTC10D-7 NTC Thermistor is a 9mW, 10Ohm Through Hole part, manufactured by Ruilongyuan. It has a P=5mm size and is RoHS compliant. It is a thermistor, a type of resistor that produces an electrical resistance that changes in relation to a change in temperature. It is a negative temperature coefficient (NTC) thermistor, meaning that its resistance decreases when the temperature rises. It can be used in automotive, home appliance, medical, and communications industries for over-temperature protection, temperature compensation, and compensation of the current.
