Overview
The Bourns MF-SVS170-0 is a polymer positive temperature coefficient (PPTC) resettable fuse from the Multifuse SVS series, designed for overcurrent protection in low-voltage circuits. It features an axial strap mount configuration with leaded termination. The device maintains a hold current of 1.7 A and trips at 4.1 A, operating within a maximum voltage of 10 V. It offers a high maximum rated current of 100 A and exhibits a typical resistance of 32 mΩ. The component functions reliably across a temperature range of -40°C to +85°C, with physical dimensions of 10.4 mm in length and 0.9 mm in height.
Feature Summary
- Provides automatic circuit recovery after fault clearance without manual replacement
- Utilizes polymer PTC technology for robust overcurrent protection in compact designs
- Features axial strap mounting for secure integration into PCB layouts
Applications
- Overcurrent protection for low-voltage electronic circuits
- Protection in consumer electronics devices

Procurement Notes
Verify the specific suffix '0' against the official Bourns datasheet to confirm exact electrical tolerances and packaging specifications. Ensure the axial strap package style matches the target PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring a 1.7 A hold current and 10 V maximum rating. The axial strap form factor is suitable for applications needing mechanical stability alongside space-constrained layouts. Evaluate the 4.1 A trip current threshold to ensure adequate protection margins for the specific load characteristics.
Part Context
This part belongs to the Bourns Multifuse SVS series, which specializes in polymer PTC resettable fuses. The series is engineered for cost-effective protection in various electronic applications. The MF-SVS170-0 specifically addresses needs for low-voltage, moderate-current protection with reliable thermal response characteristics.
Replacement Considerations
Consult the official Bourns cross-reference guide for verified substitute part numbers. Ensure any alternative component matches the 1.7 A hold current, 10 V rating, and axial strap package dimensions to maintain circuit integrity and mechanical fit.
