The new MHP Metal Hybrid PPTC device, MHP-TAT18, offers a 9VDC rating and a higher current rating than typical MHP-TAM device. This helps to meet the battery safety requirements of higher-capacity LiP and prismatic batteries found in the latest gaming PC and ultra-book products. Hybrid MHP technology connects a bimetal protector in parallel with a Polymeric Positive Temperature Coefficient (PPTC) device. The resulting MHP-TAT18 (Thermal Activation) series helps to provide resettable overtemperature protection, while utilizing the PPTC device to act as a heater and to help keep the bimetal latched until the fault is removed.


  • High current capacity with low resistance
  • Overtemperature and overcurrent protection
  • Multiple activation temperature ratings (72°C, 77°C, 82°C, 85°C, 90°C)
  • Compact size (L: 5.8mm x W: 3.80mm x H: 1.15mm) allows for ultrathin battery pack designs
  • Evaluated to UL 60730-1 and UL 60730-2-9, CAN/ CSA E60730-1, CAN/CSA E730-2-9 and IEC 60730-1 and IEC 60730-2-9
