Overview
The Bourns MF-VS170S-0 is a PPTC resettable fuse from the Multifuse series, designed for strap mount installation with axial tab slot leads. It features a holding current of 1.7 A and a trip current of 3.4 A, operating at a maximum voltage of 16 VDC. The device has a low resistance of 40 mOhms and a maximum rated current of 100 A. Physical dimensions include a length of 4.4 mm, width of 0.9 mm, and height of 0.9 mm. It operates within a temperature range of -40°C to +85°C and dissipates 1.4 W of power.
Feature Summary
- Provides overcurrent protection through positive temperature coefficient polymer technology that resets automatically after fault clearance.
- Features an axial lead configuration with a specific tab slot option designed for secure strap mounting applications.
Applications
- Protection of portable electronic devices against overcurrent conditions
- Circuit safeguarding in automotive electronics systems
- Overcurrent protection for industrial control equipment
Procurement Notes
Verify component availability status carefully as this part number is listed as End-of-Life (EOL) or discontinued by the manufacturer. Confirm final procurement channels and potential supply limitations before integrating into new designs. Check for official replacement recommendations from Bourns to ensure long-term project viability and compliance with current manufacturing standards.
Selection Notes
Select this component when a 1.7 A holding current and 16 VDC maximum voltage rating align with circuit requirements. Ensure the design accommodates the axial tab slot mounting style and physical footprint of 4.4 mm by 0.9 mm. Verify that the ambient operating environment remains within the specified -40°C to +85°C range for reliable performance.
Part Context
This device belongs to the Bourns Multifuse MF-VS series of PPTC resettable fuses. These components are engineered for compact space-constrained applications requiring reliable overcurrent protection. The series utilizes polymer technology to provide automatic reset functionality, distinguishing it from traditional one-time fusible links commonly used in similar circuit protection roles.
Replacement Considerations
Consult official Bourns documentation for confirmed substitute part numbers due to the EOL status. No direct public substitutes are verified in the provided data.
