Overview
The Bourns MF-RG800-AP is an automotive-grade polymeric PTC resettable fuse designed for circuit protection. It features a maximum operating voltage of 16V and a hold current (Ih) of up to 8A, with a trip current (It) of 13.6A. The device supports a maximum fault current of 100A and exhibits a minimum initial resistance of 5.6 mOhms. Post-trip resistance is capped at 17.5 mOhms. It operates within a temperature range of -40°C to 85°C and complies with AEC-Q200 standards.
Feature Summary
- Automotive-grade AEC-Q200 compliance ensures reliability in demanding environments.
- Polymeric construction allows automatic recovery after tripping without replacement.
- Compact radial leaded design facilitates integration into space-constrained PCB layouts.
Applications
- Automotive electronic circuits
- Consumer electronics power lines
- Industrial instrumentation protection
Procurement Notes
Verify the specific suffix 'AP' against official Bourns documentation to confirm exact electrical tolerances and packaging configuration. Ensure the selected variant matches the required hold current and voltage ratings for the target application. Cross-reference the datasheet revision date to confirm component availability and compliance status before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring robust overcurrent protection with auto-reset capabilities. The 16V rating and 8A hold current define the operational envelope. Consider the 100A max fault current capability for short-circuit scenarios. Verify thermal management requirements given the -40°C to 85°C operating range and ensure the radial lead spacing fits the PCB footprint constraints.
Part Context
This part belongs to the Bourns MF-RG Series of PTC resettable fuses. The series is characterized by fast tripping times and compact radial leaded packages. It is specifically engineered for automotive applications, meeting stringent AEC-Q200 qualification standards for durability and performance under varying environmental conditions.
Replacement Considerations
Consult official Bourns substitution guides for compatible alternatives. Generic PTC fuses may not meet AEC-Q200 automotive qualifications or match the specific 5.6 mOhm initial resistance profile. Verify that any substitute maintains the 16V voltage rating and 100A max fault current capacity.
