How PPTC Resettable Fuses Work

Protection Principle

A PPTC resettable fuse normally has low resistance during normal operating conditions. When excessive current causes the component to heat, its resistance increases significantly, reducing the current flowing through the protected circuit.

After the fault condition is removed and the component cools, its resistance can return toward its normal operating state. This resettable behavior makes the 1206L005/60WR Resettable Fuses - PPTC useful in applications where repeated overcurrent events may occur.


Installation and PCB Design Overview

Installation Guidelines

  • Verify the fuse specifications against the application's operating requirements.

  • Confirm the PCB footprint before placement.

  • Observe the recommended soldering profile.

  • Place the component in the correct PCB orientation and position.

  • Ensure the normal operating current remains within the specified limits.

  • Evaluate fault conditions when selecting the protective component.

  • Verify circuit performance after assembly.

Correct component selection and PCB installation are important for achieving reliable performance from the 1206L005/60WR Resettable Fuses - PPTC.


Use Case Example: Compact Electronic Control Board
