Littelfuse MHP-TAT18 Metal Hybrid PPTC Devices

Littelfuse MMHP-TAT18 Metal Hybrid PPTC Devices are resettable PPTCs, offering a 9VDC rating and a higher current rating than a typical MHP-TAM device. These current and voltage rating features help meet the battery safety requirements of Lithium Polymer (LiP) and prismatic batteries found in gaming PCs and ultra-book products. Littelfuse MHP-TAT18 helps to provide resettable overtemperature protection while utilizing the PPTC device to act as a heater and keep the bimetal latched until the fault is removed.

Features

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

Applications

  • Battery cell protection for high-capacity lithium polymer and prismatic cells
    • Gaming PCs
    • Notebook PCs
    • Ultra-books
