MF-R160-0-17

Overview

The Bourns MF-R160-0-17 is a radial leaded PTC resettable fuse from the MFR series, designed for overcurrent protection in low-voltage circuits. It features a 30 VDC maximum voltage rating and a 1.6 A hold current. The device trips at 3.2 A with a typical trip time of 8 seconds. Maximum fault current capability is 40 A, with an initial resistance of 105 mΩ. Operating temperature range spans -40°C to +85°C, with a radial lead spacing of 5.1 mm.

Feature Summary

• Provides automatic circuit recovery after overcurrent events without manual replacement
• Offers robust protection against short circuits and sustained overloads in low-voltage applications
• Features radial leads for reliable through-hole PCB mounting

Applications

• Low-voltage power supply output protection
• Peripheral interface circuit safeguarding
• Battery pack overcurrent protection

Procurement Notes

Verify that the specific suffix '-0-17' corresponds to the standard radial lead configuration and bulk packaging as documented in the official Bourns datasheet. Confirm RoHS compliance status and UL recognition details directly from the manufacturer's certification records before integration into production designs.

Selection Notes

Select this component when a 1.6 A hold current and 30 VDC rating align with the target circuit requirements. Ensure the 40 A maximum fault current exceeds potential short-circuit levels. Consider the 105 mΩ initial resistance impact on power loss and the -40°C to +85°C operating range suitability for the environmental conditions.

Part Context

This part belongs to the Bourns MFR series of high-density PTC resettable fuses. These devices are engineered for compact PCB layouts while maintaining high performance standards. The series provides a cost-effective alternative to traditional fuses by eliminating the need for manual replacement after tripping events.
