MHP-TAT18 Series Metal Hybrid PPTC
CHICAGO, January 22, 2018 — Littelfuse, Inc., the global leader in circuit protection, today introduced the MHP-TAT18 Metal Hybrid PPTC Battery Mini-Breaker with resettable Thermal Cut-Off (TCO). This over-temperature protection device offers a 9VDC rating and a higher current rating than similar products on the market. This new device helps circuit designers meet the battery safety requirements of the higher-capacity lithium ion polymer and prismatic battery cells found in the latest portable, battery-powered consumer products. MHP technology connects a bimetal protector in parallel with a Polymeric Positive Temperature Coefficient (PPTC) device, PPTC acts as a heater and helps keep the bimetal latched until the fault is removed.
Typical applications for the MHP-TAT18 Battery Mini-Breaker Series with resettable TCO include battery cell protection for high-capacity lithium ion polymer and Li-ion prismatic cells used in:
- ゲーム用パソコン
- ノートパソコン
- Ultrabook
- タブレット
- Other battery-powered portable devices
"Compared to similar protection devices on the market, MHP-TAT18 Metal Hybrid PPTC Mini-Breakers with thermal cut-off can handle higher currents in a smaller, thinner form factor," said Amy Chu, product manager, Electronics Business Unit at Littelfuse. "Their welding leads can also be customized to facilitate a customer's design process."
The MHP-TAT-18 Metal Hybrid PPTC Mini-Breaker Series with resettable TCO offers these key benefits:
- High current capacity and low resistance capable of handling the voltages and battery charge rates found in high-capacity lithium ion polymer and prismatic cells.
- Multiple activation temperature ratings (72°C, 77°C, 82°C, 85°C, 90°C) help to provide resettable and accurate over-temperature protection.
- Thin, compact form factor (5.8mm x 3.80mm x 1.05mm) facilitates circuit protection in ultra-thin battery pack designs.
