Littelfuse MHP Metal Hybrid PPTC Devices
Littelfuse MHP Metal Hybrid PPTC Devices are cost-effective, resettable circuit protection devices capable of 9VDC or 12VDC contact ratings, which helps to meet the battery safety requirements of higher-capacity lithium (ion) polymer and prismatic batteries. By connecting a bimetal protector parallel with a polymeric positive temperature coefficient (PPTC) device, the resulting Metal Hybrid PPTC Device offers resettable overcurrent protection. At the same time, the low resistance of the PPTC device prevents arcing of the bimetal protector at higher currents. Littelfuse MHP Metal Hybrid PPTC Devices are ideally suited for applications such as cordless battery tools, E-bikes, back-up uninterruptable power supplies (UPS), and back-up power for medical devices.
