Overview
The MF-RG900-2 is a polymeric positive temperature coefficient (PPTC) resettable fuse manufactured by Bourns Inc. It features a radial through-hole package with a maximum voltage rating of 16V and a hold current of 0.9A. The device offers a trip current of 1.5A and a maximum fault current of 100A. Physical dimensions include a length of 14mm, height of 21.7mm, and lead spacing of 5.1mm. Power dissipation is rated at 3.3W.
Feature Summary
- Polymeric PTC technology provides automatic reset functionality after fault conditions clear
- Radial through-hole construction facilitates standard PCB mounting processes
- High-reliability design suitable for demanding circuit protection applications
Applications
- Automotive electronics circuits
- Consumer electronic device protection
- Industrial control system overcurrent safeguarding
Procurement Notes
Verify the specific datasheet version to confirm compliance with automotive standards if required. Ensure the radial lead spacing matches the target PCB footprint. Confirm that the 16V rating aligns with the operating voltage of the protected circuit. Check for any specific packaging or handling requirements during procurement.
Selection Notes
Select this component when a low-voltage, high-current resettable fuse is needed. The 0.9A hold current suits circuits requiring precise overcurrent limits. Consider the 100A maximum fault current capability for robust short-circuit protection. Evaluate the physical size constraints against the available board space before finalizing the selection.
Part Context
This part belongs to the Bourns MF-RG series of multifuse products. The series is designed for general-purpose circuit protection using PPTC materials. These components are widely used in industries requiring reliable, non-fusible overcurrent protection solutions.
Replacement Considerations
Consult official Bourns documentation for direct substitutes. Verify electrical ratings and physical dimensions match exactly. Cross-reference with other manufacturers only if specifications are identical.
