Introduction

PTC resettable fuses are electronic protection devices that combine low heat resistance and a slow-blow current limiting principle, allowing them to be used for a variety of applications. The most popular of these is the PTGL4SAS100K2B51B0, which is a type of resettable fuse designed for use in automotive electronics. It can be used for up to 18A applications, depending on the type of device it is protecting.

Functional Principle

The PTGL4SAS100K2B51B0 uses a polymeric positive temperature coefficient (PPTC) device to detect an overcurrent condition. When an overcurrent is detected, the PPTC device expands and creates a large resistance, effectively cutting off the circuit. The resistance remains high until the current drops below the rated level and the PPTC device then contracts and the resistance returns to its original low level. This process allows the PTGL4SAS100K2B51B0 to automatically reset after the current has dropped below its rated level.
