MF-NSMF075/8X-2

Ptc Resettable Fuses Overview

The MF-NSMF075/8X-2 is a polymeric positive temperature coefficient (PPTC) resettable fuse from the MF-NSMF series, manufactured by Bourns Inc. Designed for surface-mount applications in the 1206 (3216 Metric) package, this component provides overcurrent protection with an 8 V voltage rating and a 750 mA hold current. It features a trip current of 1.5 A and a maximum resistance of 350 mΩ. The device is rated for automotive use under AEC-Q200 standards, offering surge current capacity up to 100 A.

Ptc Resettable Fuses Feature Summary

• Polymeric PPTC technology enables automatic circuit restoration after fault clearance without manual replacement.
• AEC-Q200 qualification ensures reliability and performance consistency for demanding automotive electronic environments.
• Surface-mount 1206 package design facilitates automated assembly and compact PCB layout integration.

Ptc Resettable Fuses Applications

• Automotive electronics circuits requiring AEC-Q200 compliant overcurrent protection
• Portable consumer devices needing compact surface-mount resettable fuses
• Industrial control systems utilizing low-voltage DC power distribution

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix /8X-2 matches the required reel packaging configuration and tape-and-reel specifications for your automated placement equipment. Confirm that the 1206 footprint aligns precisely with your PCB design guidelines to ensure proper solder joint integrity during reflow processes.

Ptc Resettable Fuses Selection Notes

Select this component when designing circuits operating at or below 8 V where space constraints necessitate a 1206 SMD form factor. Ensure the expected operating current remains below the 750 mA hold rating while accounting for ambient temperature derating curves provided in the datasheet to prevent nuisance tripping during normal operation.

Ptc Resettable Fuses Part Context

This part belongs to Bourns' MF-NSMF series of non-magnetic, low-profile resettable fuses. The series is engineered for high-reliability applications, particularly in automotive sectors where vibration resistance and compact size are critical. The MF-NSMF line offers various hold current options within the same package family to support diverse circuit protection needs.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 1206 package, 8 V rating, and 750 mA hold current. Verify equivalent AEC-Q200 certification if used in automotive contexts. Cross-reference impedance and trip characteristics with competitor PPTC devices to ensure functional compatibility in the target application.
