Overview
The Bourns MF-R900-2-14 is a radial leaded PTC resettable fuse from the Multifuse series. It features a hold current of 9.0 A and a trip current of 18.0 A at ambient temperature. The device supports a maximum voltage of 30 VDC and offers a high fault current rating of 100 A. Its initial resistance is typically 5.5 mOhms, with a power dissipation of 3 W. The component operates within a temperature range of -40°C to +85°C and utilizes cured flame-retardant epoxy polymer insulation.
Feature Summary
- Provides automatic circuit protection through reversible thermal switching action upon overcurrent events.
- Encased in cured flame-retardant epoxy polymer insulation that meets UL 94V-0 safety requirements.
- Designed for PCB mounting with radial leads for straightforward integration into electronic assemblies.
Applications
- Low-voltage power supply overload protection
- Computer and peripheral circuit safeguarding
- General electronics equipment protection
Procurement Notes
Verify the specific suffix '-14' against official manufacturer documentation to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required 30 VDC maximum voltage rating for the target application. Cross-reference the hold current tolerance with system design margins to guarantee reliable operation under varying thermal conditions.
Selection Notes
Select this component when applications require a 9.0 A hold current and 30 VDC operating voltage. Consider the 100 A maximum fault current rating for surge handling capabilities. Evaluate the 3 W power dissipation limit against ambient thermal constraints. Confirm compatibility with standard PCB mounting techniques using radial leads.
Part Context
This part belongs to the Bourns Multifuse MF-R series of PTC resettable fuses. These components are engineered for load protection in low-voltage environments. The series provides a cost-effective alternative to traditional fuses by offering reusable circuit interruption without manual replacement.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Verify electrical parameter equivalence before considering any alternative components from other manufacturers.
