Automatically resets after fault conditions are cleared without manual intervention
Halogen-free and RoHS compliant construction

Ptc Resettable Fuses Applications

Protection of electric motors in commercial appliances
Transformer protection in home appliances
Circuit safeguarding against stall or lost neutral conditions

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix designation when ordering, as variations exist within the LVR series. Confirm that the required voltage rating aligns with the 120 VAC/VDC specification rather than higher-rated variants. Ensure the PCB layout accommodates the radial lead spacing and physical dimensions specified in the official datasheet to guarantee proper mounting and thermal performance.

Ptc Resettable Fuses Selection Notes

Select this component for applications requiring reliable protection against mechanical overloads and overheating in devices connected to 120 VAC lines. The 250 mA hold current suits low-power motor or transformer loads. Consider the 20 A maximum interrupting rating for surge scenarios. Verify compatibility with the target operating temperature range and ensure the radial package fits the available board space constraints.
