The new PPTC series PFTA, PFTB, PFTC, and PFTL offers reliable resettable protection against both overcurrent and overheating in today’s electronic systems.
When a fault occurs, the polymer PTC device automatically increases its resistance, helping prevent damage from overloads or short circuits without the need to replace traditional fuses.
This portfolio includes both radial leaded and surface-mount (SMD) options, with current ratings ranging from 0.05 A to 5 A and voltage ratings up to 72 V. Built using UL-compliant, flame-retardant materials and designed for compatibility with automated assembly, these components are well-suited for high-volume industrial production.
Typical use cases span a wide range of applications, including energy storage systems, power supplies, industrial equipment, consumer electronics, automotive systems, 
wearables, SSDs, and lithium-ion batteries.
The compact PFTL SMD series is particularly useful for space-constrained designs, enabling higher integration in smaller form factors.
