Battery Mini-Breakers Metal Hybrid PPTC > MHP Series MHP-TAC Series Breaker RoHS Description The new Metal Hybrid PPTC device, MHP-TAC, offers higher voltage rating (12VDC) and smaller size than typical MHP-TAM devices. MHP-TAC helps to meet the battery safety requirements of higher-capacity Lithium (Ion) Polymer and Prismatic batteries found in most mobile devices such as laptop PC’s, tablets, and smart phones. MHP technology connects a bimetal protector in parallel with a Polymeric Positive Temperature Coefficient (PPTC) device. The PPTC device is to act as a heater and to help keep the bimetal latched until the fault is removed. The resulting MHP-TAC helps to provide resettable overtemperature protection.

Operating Temperature Range -30~100°C Precautions for Electrical Characteristics Precautions for Rating 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. a. The power supply voltage must be less than the rated voltage of the device. Operation above the voltage rating may result in device damage, smoking or flame. b. Designs must be selected in such a manner that the device hold current is higher than the normal current value in the circuit and that the device trip current is lower than the abnormal current value. Selecting device hold current and trip current values that are too low for the application may interrupt the circuit under normal usage conditions. c. This product should not be used in an application where the maximum interrupt current can be exceeded in a short circuit condition. d. The devices are intended for protection against damage caused by occasional over current or over temperature fault conditions and should not be used when repeated fault conditions or prolonged trip events are anticipated. e. The devices may not perform as specified if mechanical pressure is added while the device is in the tripped state or exposed to temperature conditions over 100°C. 1.2 1.2 B E 0.1±0.01 0.1 (.15) A 0.1 0.1±0.01 D (.15) C 1.2 1.2 2.0 Dimensions Cover Disc Notes: • Unspecified dimensions, tolerance should be +/-0.1mm • Dimensions in brackets are for reference Dimple (Optional) A Unit = mm B Base Terminal Contact C PPTC Arm Terminal D Dimple (Optional) E MIN MAX MIN MAX MIN MAX MIN MAX MIN MAX 4.65 4.85 0.75 0.85 2.7 2.9 3.1 3.3 3.1 3.3 © 2018 Littelfuse, Inc.

The power supply voltage must be less than or equal to the rated voltage of the device. Operation above the voltage rating may result in device damage, smoke or flame. d. The devices are intended for protection against damage caused by occasional over current or over temperature fault conditions and should not be used when repeated fault conditions or prolonged trip events are anticipated. b. Designs must be selected in such a manner that the device hold current is higher than the normal current value in the circuit. Selecting device hold current that is too low for the application may interrupt the circuit under normal usage conditions. e. The devices may not perform as specified if mechanical pressure is added while the device is in the tripped state or exposed to temperature conditions over 100°C or in temperature conditions under -30°C. c. This product should not be used in an application where the maximum short circuit current available exceeds the rated maximum breaking current of the product. Handling Precautions a. 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. b. When welding product terminals or mounting the breaker on 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. • Do not apply more than 10N bend force to product. (Fig. 1) • Do not apply more than 1.5cN*m twist torque to the product. (Fig. 2) • Do not apply more than 20N deflection force to product. (Fig. 3) • Do not apply more than 2N force to the terminals. (Fig. 4) • Do not apply more than 0.6cN*m twisting torque to the terminals. (Fig. 5) • Do not bend the terminals more than 45° at the end. (Fig. 6) • Should not twist terminals more than 20°C with breaker body fixed. c. 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. d. 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. e. Please avoid putting the stress on the device, as listed above, when a jig, fitting or additional welding process is used. Please re-confirm the resistance value whenever a new process is added.
