Overview
The Bourns MF-SM075-2-006 is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse from the MF-SM Series. It functions as an overcurrent protection device that automatically resets after cooling, eliminating the need for replacement following fault conditions. Designed for high-reliability applications, this component provides robust circuit protection against excessive current and short circuits while maintaining low resistance during normal operation.
Feature Summary
- Surface-mount construction for automated assembly
- Automatic reset capability after fault clearance
- High reliability in harsh environments
Applications
- Portable electronic devices
- Laptop computers and peripherals
- Automotive electronics
Procurement Notes
Verify the specific suffix codes on the component marking to ensure exact match with design requirements. Confirm package dimensions and termination compatibility with PCB layout. Review manufacturer datasheets for derating curves and ambient temperature effects before finalizing procurement specifications.
Selection Notes
Select based on hold current and trip current ratings relative to the circuit's maximum operating current. Ensure voltage rating exceeds the system's maximum potential. Consider thermal environment and space constraints when choosing between through-hole and surface-mount variants within the series.
Part Context
This part belongs to the MF-SM Series of surface-mount PPTC devices. The series is engineered for compact consumer and industrial electronics requiring reliable overcurrent protection without manual intervention. It complements Bourns' broader portfolio of circuit protection components designed for modern miniaturized designs.
Replacement Considerations
Consult official substitution guides for equivalent parts with matching electrical characteristics. Verify physical footprint compatibility if replacing in existing assemblies. Ensure new components meet same safety certifications and environmental compliance standards.
