The MHP30-36 is a metal hybrid polymeric positive temperature coefficient (PPTC) device that combines a bimetal protector in parallel with a PPTC device. The hybrid device offers 30-A hold current and an initial resistance of less than 2 mΩ. The PolySwitch (PPTC) polymeric positive temperature coefficient provides resettable overcurrent, overtemperature protection. The PolySwitch PPTC device is a conductive polymer-based thermistor. It is characterized by either negative temperature coefficient behavior (NTC) where the resistance of the device decreases with temperature, or positive temperature coefficient (PTC), behavior where the device resistance increases with temperature. The PPTC is made from a composite of semi-crystalline polymer and conductive particles.
