Littelfuse – Resettable Fuses

Littelfuse POLY-FUSE devices are Polymeric Positive Temperature Coefficient (PPTC) devices which offer a resettable overcurrent protection alternative. Wherever a replacement of the protection components in case of need is not possible, the use of resettable fuses is indispensable. Another key role plays miniaturization. The available space on a circuit board is limited for which reason the protection device has to meet this requirement as well.

Features and benefits:

  • Reduced repair and replacement costs
  • Increased reliability
  • Combined overcurrent and overtemperature protector in one device
