PFRA.600

Ptc Resettable Fuses Overview

The SCHURTER PFRA.600 is a resettable polymeric positive temperature coefficient (PPTC) fuse designed for overcurrent protection in electronic circuits. It utilizes a radial leaded package configuration suitable for through-hole PCB mounting. The component operates with a maximum voltage rating of 30 VDC and maintains a hold current of 120 mA under normal conditions. Upon detecting an overload, the device trips at 240 mA, providing reliable circuit interruption. It supports a maximum fault current of 40 A and features a low resistance of 1.29 Ohms to minimize power loss during operation. The unit functions within a temperature range of -40°C to +85°C.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit recovery after fault clearance without manual replacement
• Radial leaded construction facilitates standard through-hole PCB integration
• Low impedance design reduces thermal impact on sensitive downstream components

Ptc Resettable Fuses Applications

• Overcurrent protection for portable consumer electronics
• Battery pack safeguarding in mobile devices
• Interface circuit protection for communication modules

Ptc Resettable Fuses Procurement Notes

Verify that the specific batch matches the manufacturer's latest datasheet revisions, as PPTC characteristics can vary between production runs. Confirm that the radial lead spacing and seated height dimensions align precisely with the target PCB footprint to ensure mechanical stability. Check for any regional compliance certifications required by the end-product regulations before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component when a compact, self-resetting solution is required for low-voltage DC applications. Ensure the operating current remains below the 120 mA hold threshold to prevent nuisance tripping during normal operation. Evaluate the ambient temperature environment to guarantee the device stays within its specified operational limits while maintaining effective thermal dissipation capabilities.

Ptc Resettable Fuses Part Context

This part belongs to Schurter's PFRA series of polymeric resettable fuses, which are engineered for high-reliability applications requiring repeated trip cycles. The series offers various current ratings to accommodate different circuit protection needs. The PFRA.600 specifically targets lower current requirements compared to higher-rated siblings in the same product family.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 30VDC rating, 120mA hold current, and radial package form factor. Verify that alternative PPTC devices maintain equivalent trip currents and maximum fault current capabilities to ensure identical protection performance.
