MF-R050-0-17

Ptc Resettable Fuses Overview

The Bourns MF-R050-0-17 is a radial leaded PPTC resettable fuse from the MF-R series. It features a hold current of 500 mA and a trip current of 1 A at ambient temperature. The device supports a maximum voltage of 60 VDC and can interrupt fault currents up to 40 A max. Initial resistance is typically 770 mOhms. It operates within a temperature range of -40°C to +85°C with a 5.1 mm lead spacing.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection against overcurrent conditions through positive temperature coefficient polymer technology.
• Offers reliable resettable functionality without requiring manual replacement after fault clearance.
• Designed for PCB mounting with radial leads for standard through-hole integration.

Ptc Resettable Fuses Applications

• Overcurrent protection in portable electronic devices
• Circuit protection for peripheral interfaces

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure correct packaging and variant selection. Confirm RoHS compliance status and lead-free specifications for your assembly requirements. Cross-reference the Mouser number 652-MF-R050-0-17 for accurate distributor identification and availability checks.

Ptc Resettable Fuses Selection Notes

Select this component when a 500 mA hold current and 60 VDC rating are required for low-current circuit protection. Ensure the application current remains below the hold current threshold during normal operation. Verify that the expected fault current does not exceed the 40 A maximum interrupting rating of the device.

Ptc Resettable Fuses Part Context

This part belongs to the Bourns MF-R series of multifuse resettable fuses. These components utilize conductive polymer technology to provide dual protection against overcurrent and excessive temperature. The series is widely used in consumer electronics and industrial applications requiring compact, self-resetting circuit protection solutions.

Ptc Resettable Fuses Replacement Considerations

Consult official substitution guides for equivalent ratings. Generic replacements must match the 500 mA hold current, 60 VDC voltage rating, and radial package dimensions to ensure compatibility.
