The rapidly expanding market for ultra-thin portable electronic devices, such as media tablets and ultra-thin PCs, has created demand for very thin, low-profile, lightweight and high-capacity Lithium Polymer (LiP) and prismatic cells. MHP-TA Device: MHP with Thermal Activation MHP-TA Device: MHP with Thermal Activation A new MHP (Metal Hybrid PPTC) device, the MHP-TA device, offers a 9VDC rating and a higher current rating than typical battery strap devices. This helps them meet 4 the battery safety requirements of higher-capacity LiP and prismatic batteries found in the latest tablet and ultra-thin computing products. Hybrid MHP technology connects a bimetal protector in parallel with a PPTC (polymeric positive temperature coefficient) device. The resulting MHP-TA (Thermal Activation) series helps 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.

Suggested storage temperature (except for packaging material) Temperature: -10C - 40C Humidity: 75%RH (max) The following environments should be avoided for storage: 4 Areas with salt air or with corrosive gas, such as Cl2, H2S, NH3, SO2 and NOx. Areas exposed to direct sunlight. Areas outside of the suggested storage temperature range, as indicated above. Precautions for Handling The device is composed of plastic parts, please do not clamp or dent the housing with a tool as this might cause a resistance increase and product damage. When welding product terminals or mounting the breaker on a battery (cell), please be careful not to apply excessive bending, twisting or force on the product and terminals. The excessive stress might cause a resistance increase or product damage. Please refer to following cautions: 1. Do not apply more than 10N bend force to product. (Fig. M3) 2. Do not apply more than 1.5cN/m twist torque to the product. (Fig. M4) 3. Do not apply more than 20N deflection force to product. (Fig. M5) 4. Do not apply more than 2N force to the terminals. (Fig. M6) 5. Do not apply more than 0.6cN/m twisting torque to the terminals. (Fig. M7) 6. Do not bend the terminal base more than 20 when the product is mounted in a fixed position. (Fig. M8) Figure M3 Figure M4 Figure M5 Figure M6 Figure M7 Figure M8 20 20 20 20 Product terminals can be welded using direct welding and series welding methods. In either case, please use a suitable jig so that the device will not be subjected to the stress conditions listed above. Pull strength and detach strength of the terminal welds are per user requirements. However, if the welding is controlled by resistance, the measurement should be made as close as possible to the weld point by a "4-point clip method" using milliohm meter to ensure accuracy. Avoid putting stress on the device, as listed above, when a jig, fitting or additional welding process is used. Please reconfirm the resistance value whenever a new process is added. 30 RoHS Compliant, ELV Compliant 2013_CP_S04-CatMHP.indd 30 8/3/13 11:10 AM Packaging and Marking Information for MHP-TA Devices Part Number Bag Quantity T&R Quantity Standard Package Part Marking Agency Recognition MHP-TA15-9-72 2,500 - 50,000 Lot ID#, Control# & Co.
