Littelfuse MHP-TAC Mini-Breakers
Littelfuse MHP-TAC Mini-Breakers are metal hybrid PPTC devices that are in a smaller size than typical MHP-TAM devices. The MHP technology connects a bimetal protector in parallel with a Polymeric Positive Temperature Coefficient (PPTC) device. These mini-breakers act as a heater and keep the bimetal latched until the fault is removed. The MHP-TAC helps to provide resettable overtemperature protection and meet the battery safety requirements of higher-capacity Lithium (Ion) Polymer and Prismatic batteries. These are found in most mobile devices such as laptop PC’s, tablets, and smartphones. Littelfuse MHP-TAC Mini-Breakers are available in 4.75mm x 2.8mm x 0.8mm dimensions that allow for ultra pack designs.
