PPTC: Compact Protection for Maximum Reliability
The new PPTC series PFTA, PFTB, PFTC and PFTL provide reliable resettable overcurrent and overtemperature protection for modern electronic applications. In the event of a fault, the polymer PTC device automatically increases resistance to effectively protect systems against overloads and short circuits — without replacing fuses.
The portfolio includes radial leaded and SMD versions with current ratings from 0.05 to 5 A and voltage ratings up to 72 V. UL-compliant flame-retardant materials and compatibility with automated assembly processes make these series ideal for industrial high-volume applications.
Applications
Typical applications include energy storage systems, power supplies, industrial electronics, consumer electronics, automotive systems, wearables, SSDs and Li-ion batteries. The compact PFTL SMD series additionally enables space-saving designs with high integration density.
