Overview
The Bourns MF-SVS170N-0 is a PTC resettable fuse from the Multifuse MF-SVS series, designed for strap mount installation with axial leads. It features a holding current of 1.7 A and a trip current of 4.1 A at rated voltage. The device supports a maximum voltage of 10 V and offers a maximum fault current rating of 100 A. Its initial resistance is 32 mOhms, and it operates within a temperature range of -40°C to +85°C. Physical dimensions include a length of 10.4 mm, width of 3.9 mm, and height of 0.9 mm.
Feature Summary
- Provides overcurrent protection through polymer positive temperature coefficient (PPTC) technology that resets automatically after fault conditions clear.
- Utilizes an axial leaded strap mount configuration suitable for secure mechanical attachment in circuit layouts.
- Designed to eliminate nuisance tripping caused by ambient temperature variations while maintaining robust short-circuit protection.
Applications
- Overcurrent protection for automotive electronic circuits
- Surge protection in high-reliability industrial equipment
- Fault protection for communication systems and consumer electronics
Procurement Notes
Verify the specific suffix N-0 against the official Bourns datasheet to confirm the exact physical dimensions and termination style match your design requirements. Ensure the operating environment remains within the specified -40°C to +85°C range to maintain performance integrity. Confirm RoHS compliance status directly with the manufacturer documentation prior to integration.
Selection Notes
Select this component when a low-profile axial strap mount fuse is required for 10 V circuits carrying up to 1.7 A continuously. Compare the 32 mOhms resistance and 10.4 mm length against board space constraints. Evaluate the 4.1 A trip threshold against expected surge currents to ensure appropriate protection without false activation during normal operation peaks.
Part Context
This part belongs to the Bourns Multifuse MF-SVS series, which specializes in polymer PTC resettable fuses for general circuit protection. The series provides cost-effective solutions for eliminating short-circuit risks in various electronic assemblies. These components are engineered to offer flexibility in layout design compared to traditional radial leaded parts.
Replacement Considerations
Consult the official Bourns replacement guide for verified substitutes. Cross-reference holding current, voltage ratings, and physical dimensions to ensure compatibility. Do not assume functional equivalence based solely on series naming conventions without verifying specific electrical parameters.
