Overview
The Bourns MF-SD013/250-2 is a surface-mount polymer PTC resettable fuse from the Multifuse series. It features a maximum operating voltage of 60V and a hold current (Ih) of 130mA. The device trips at a maximum current of 3A and offers initial resistance between 4Ω and 20Ω, with post-trip resistance up to 16Ω. Designed for -40°C to +85°C operation, it utilizes a 2-SMD package measuring 8.90mm x 7.20mm.
Feature Summary
- Polymer PTC technology provides automatic circuit protection that resets after fault clearance
- Surface-mount construction enables automated assembly on printed circuit boards
- Certified by cURus and TUV agencies for international safety compliance
Applications
- Portable electronic devices requiring overcurrent protection
- Consumer electronics circuits
- Industrial instrumentation power lines
Procurement Notes
Verify component authenticity through authorized Bourns distributors or certified partners. Confirm RoHS3 compliance status and MSL level 1 handling requirements during storage. Ensure ordering suffixes match specific packaging formats such as tape and reel or cut tape. Validate datasheet revisions against procurement documents to guarantee parameter accuracy.
Selection Notes
Select this component when space-constrained designs require surface-mount overcurrent protection. Evaluate thermal derating curves for ambient temperatures exceeding standard ratings. Compare trip times and residual voltage drops against downstream component tolerances. Ensure the hold current exceeds maximum normal operating current while maintaining adequate margin for inrush currents.
Part Context
This part belongs to the Multifuse MF-SD/250V series, designed specifically for surface-mount applications. It complements radial leaded variants like the MF-SM series by offering compact footprint solutions. The series supports various current ratings within the same physical envelope family.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other Bourns Multifuse SMD series only if electrical parameters and mechanical dimensions align precisely.
