The Tyohm WMZ12A-85LB10RMAP150B3.5-H6B is an PTC thermistor with a through hole design and is RoHS compliant. It is a PTC (positive temperature coefficient) thermistor, which differentiates itself from an NTC (negative temperature coefficient) thermistor by having a rising electrical resistance with increasing temperature, rather than a decreasing resistance. It has a maximum operating temperature of 85? and a maximum continuous current rating of 10A. It is ideal for over-current protection in applications such as relay control, motor control, lighting control, and more. The thermistor also has an epoxy sealed enclosure for extra protection.
