The new 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.
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 (72°C, 77°C, 82°C, 85°C,
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 used in:
• Gaming PCs
• Notebook PCs
• Ultra-book
• Tablets
• Battery-powered portable devices

Precautions for Electrical Characteristics:
a. Device electrical characteristics may change depending on
installation conditions. Users should independently evaluate the
suitability of and test each product in their own application. b.
If any terminal or lead extensions are added to the device,
especially in the case of high current discharging, the device
performance may be negatively impacted due to variations in welding
methods or materials. Please avoid designs that might cause heat to
be generated around the joints of the lead extensions or on the
extended terminals. c. SMT solder reflow, wave-soldering and manual
soldering irons are not permitted.
