Overview
The Bourns MF-SM075/60-2 is a surface-mount PPTC resettable fuse from the Multifuse SM series. It features a hold current of 750 mA and a trip current of 1.5 A, rated for a maximum voltage of 6 VDC. The device offers a maximum fault current rating of 40 A and an initial resistance of 350 mOhms. Designed for automotive applications, it holds AEC-Q200 qualification. The component operates within a temperature range of -40°C to +85°C and utilizes an 0805 (2012 metric) package with dimensions of 2.3 mm length, 1.5 mm width, and 1.25 mm height.
Feature Summary
- Provides overcurrent protection through automatic resistance increase during fault conditions
- Automotive-grade reliability certified under AEC-Q200 standards
- Compact surface-mount design suitable for high-density PCB layouts
Applications
- Automotive electronic circuit protection
- Portable device power line safeguarding
- Industrial control system input/output protection
Procurement Notes
Verify the specific suffix designation against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging configurations. Ensure the procurement source provides valid traceability documentation. Confirm that the delivered components match the specified AEC-Q200 automotive grade requirements for your intended application environment.
Selection Notes
Select this component when designing circuits requiring low-voltage protection with a 750 mA hold current. The 0805 package size is appropriate for space-constrained designs. Consider the 350 mOhms initial resistance for power loss calculations. Ensure the operating environment remains within the specified -40°C to +85°C temperature range for optimal performance.
Part Context
This part belongs to the Bourns Multifuse SM series of resettable fuses. The series is characterized by its small footprint and suitability for surface-mount technology. It serves as a reusable alternative to traditional fusible links in modern electronics, offering consistent performance across repeated thermal cycling events without requiring replacement after tripping.
Replacement Considerations
Consult the official Bourns substitution guide for verified equivalents. Generic cross-references may not maintain the required AEC-Q200 automotive qualification or precise dimensional tolerances.
