MF-VS210S-0

Overview

The MF-VS210S-0 is a strap-mount PTC resettable fuse from the Bourns MF-VS series. It features axial termination and operates within a temperature range of -40°C to +85°C. Key electrical parameters include a hold current of 2.1 A, trip current of 4.7 A, maximum voltage of 6 VDC, and maximum fault current of 100 A. Initial resistance is typically 30 mΩ (min 18 mΩ), with post-trip resistance up to 60 mΩ. The component measures 11.5 mm in length and 0.9 mm in height, with a power dissipation rating of 1.5 W.

Feature Summary

• Provides automatic circuit protection through self-resetting polymer positive temperature coefficient technology.
• Designed for high-current applications with a maximum fault current rating of 100 A.
• Utilizes a strap-mount configuration with axial leads for secure mechanical attachment.

Applications

• Overcurrent protection in portable electronic devices
• Circuit safeguarding in automotive electronics
• Protection for battery packs and power supply lines

Procurement Notes

Verify that the specific suffix 'S' denotes the strap-mount package variant, distinct from standard leaded versions. Confirm the maximum operating voltage requirement aligns with the 6 VDC limit specified in the datasheet. Ensure the ambient temperature conditions do not exceed the +85°C upper boundary to maintain reliable tripping characteristics.

Selection Notes

Select this component when a low-profile, high-current protection solution is required for space-constrained designs. The 2.1 A hold current suits moderate load applications, while the 100 A interrupting capacity handles significant fault events. Consider the 6 VDC voltage rating carefully, as it is lower than standard 12 V or 24 V system fuses.

Part Context

This part belongs to the Bourns MF-VS series of resettable fuses, which are engineered for high-reliability circuit protection. The series offers various current ratings and mounting styles, including surface mount and strap options, catering to diverse industrial and consumer electronics requirements.

Replacement Considerations

Direct substitutes may include other Bourns MF-VS series parts with matching 2.1 A hold current and 6 VDC rating. Verify physical dimensions and terminal type compatibility before replacement.
