Overview
The Bourns MF-RG900-0 is a polymeric positive temperature coefficient (PPTC) resettable fuse from the MF-RG series, designed for radial leaded rectangular packaging. It features a voltage rating of 16 VDC and a holding current of 9 A. The device trips at 15.3 A with a maximum trip time of 12 seconds. It has an initial resistance minimum of 4 mOhms and supports a maximum current of 100 A. This component complies with AEC-Q200 automotive-grade standards.
Feature Summary
- Provides overcurrent protection through automatic reset functionality upon cooling after tripping
- Complies with AEC-Q200 automotive-grade qualification standards for reliability
- Utilizes a compact radial leaded design suitable for space-constrained circuit boards
Applications
- Automotive electronic circuit protection
- Low-voltage DC power line safeguarding
- Industrial control system overcurrent defense
Procurement Notes
Verify the specific suffix '0' against the official Bourns datasheet to confirm the exact hold current and package variant. Ensure the application environment remains within the 16 VDC rating and that ambient temperatures do not derate the 9 A holding current below the required circuit threshold. Confirm AEC-Q200 compliance requirements are met for automotive deployments.
Selection Notes
Select this component when a low-resistance, high-current PPTC fuse is required for 16 VDC systems. The 9 A holding current and 15.3 A trip point define the protection threshold. Consider the radial leaded form factor for through-hole mounting constraints. Verify that the 12-second trip time aligns with the transient tolerance of the protected load.
Part Context
This part belongs to the Bourns MF-RG series of multifuse products. The series is characterized by fast tripping times and compact rectangular packages. It serves as a reusable alternative to traditional one-time fuses in circuits requiring frequent maintenance or inaccessible locations.
Replacement Considerations
Consult the official Bourns replacement guide for direct equivalents. Ensure substitute parts match the 16 VDC rating, 9 A hold current, and radial leaded configuration. Verify AEC-Q200 compliance if used in automotive applications.
