The new PPTC series PFTA, PFTB, PFTC, and PFTL offers reliable, resettable protection against overcurrent and overtemperature for modern electronic applications. In the event of a fault, the polymer PTC element automatically increases the resistance to effectively protect systems against overload and short circuits without the need to replace fuses.
The portfolio includes variants with radial connections and SMD versions, with current ratings from 0.05 to 5 A and voltage ratings up to 72 V. Flame-retardant materials that meet UL standards and compatibility with automated assembly processes make these series ideal for high-volume industrial applications.
Applications
Typical applications include energy storage systems, power supplies, industrial electronics, consumer electronics, automotive systems, wearables, SSDs, and Li-ion batteries. Furthermore, the compact PFTL SMD series enables space-saving designs with a high integration density.
