The NTC 5D-7 with NTC Thermistors 10mW 5Ohms Through Hole,P=5mm RoHS manufactured by Ruilongyuan is an electronic part that is typically used as a temperature sensing device. It is a negative temperature coefficient (NTC) thermistor which means that its electrical resistance decreases as its temperature increases. It is rated at 10mW and 5ohms resistance at 25?. It is designed to have a through-hole mounting, with a 5mm pin pitch. It is RoHS compliant as it does not contain any hazardous substances in its construction.
