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.



  • Miniature Thermal Cutoff (TCO) device
  • High current capacity, low resistance
  • Overtemperature and overcurrent protection for lithium polymer and prismatic cells  
  • Multiple activation temperature ratings (72℃,77℃,82℃,85℃,90℃)
  • Compact size (L:5.8mm x W:3.80mm x H: 1.05mm) allows for ultra-thin battery pack designs


Battery cell protection for high-capacity Lithium Polymer and Prismatic cells used in:

  • Gaming PCs
  • Notebook PCs
  • Ultrabook
  • Tablets
