Overview
The Bourns MF-SVS175-0 is a resettable PPTC fuse from the Multifuse SVS series, designed for strap mounting with axial leads. It features a holding current of 1.75 A and a trip current of 4.2 A. The device supports a maximum voltage of 10 V and offers a maximum rated current of 100 A. Its initial resistance is 22 mOhms. The component operates within a temperature range of -40°C to +85°C. Physical dimensions include a length of 24 mm, width of 3.9 mm, and height of 0.9 mm.
Feature Summary
- Provides overcurrent protection through automatic resistance increase upon thermal activation
- Utilizes polymer positive temperature coefficient technology for reliable circuit safeguarding
- Features axial leaded construction optimized for secure strap mounting applications
Applications
- Low-voltage electronic circuit protection
- Power supply input protection
- Battery pack safeguarding
Procurement Notes
Verify that the specific part number matches the required electrical ratings, particularly the 1.75 A holding current and 10 V maximum voltage. Confirm the axial strap mount style aligns with the PCB layout or assembly requirements. Ensure compliance with RoHS directives if applicable to the final product specifications. Cross-reference datasheet parameters against system design constraints before procurement.
Selection Notes
Select this component when low operating voltage and moderate current levels are required. The 10 V rating limits suitability to low-power circuits. Consider the 22 mOhms resistance for minimal voltage drop impact. Evaluate the 1.75 A holding current against normal operational loads to prevent nuisance tripping. The axial strap package requires specific mechanical integration compared to surface-mount alternatives.
Part Context
This device belongs to the Bourns Multifuse SVS series, which focuses on strap-mounted resettable fuses. The series provides cost-effective overcurrent protection solutions. The MF-SVS175-0 represents a specific variant within this family, distinguished by its 1.75 A current rating and axial lead configuration suitable for robust mounting methods.
Replacement Considerations
Consult official Bourns documentation for direct cross-references. Verify that any substitute maintains identical holding current, trip current, and voltage ratings. Ensure physical dimensions and mounting style compatibility. Check for equivalent thermal characteristics and resistance values to guarantee circuit performance parity.
