MF-RG1000-2

Overview

The Bourns MF-RG1000-2 is an automotive-grade PTC resettable fuse designed for circuit protection. It features a hold current of 10A and a trip current of 17A, with a maximum voltage rating of 16V. The device exhibits a maximum post-trip resistance (R1) of 10.2 mOhms and operates within a temperature range of -40°C to +85°C. Packaged in a radial leaded format measuring 16.5 x 3 x 21.7mm, it supports through-hole mounting on PCBs. The component is qualified under AEC-Q200 standards and is supplied in tape and reel packaging.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q200 standards
• Compact radial leaded design suitable for space-constrained PCB applications
• Fast tripping response for effective overcurrent protection

Applications

• Automotive electronic circuit protection
• Power supply input protection
• Signal line surge suppression

Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration, as standard variants may differ from tape and reel options. Ensure the selected part number matches the required hold and trip current specifications for the target application. Confirm that the voltage rating aligns with system requirements. Check for any additional qualification certifications beyond AEC-Q200 if mandated by the end product. Validate the physical dimensions against the PCB footprint during the design phase.

Selection Notes

Select this component when automotive reliability and compact form factor are prioritized. The low post-trip resistance minimizes power loss during normal operation. Consider the thermal environment, as the operating range extends to -40°C. The radial package facilitates easy insertion into existing through-hole designs. Evaluate the trip current margin relative to the nominal load current to ensure proper protection without nuisance tripping.

Part Context

This part belongs to the Bourns MF-RG series of PTC resettable fuses, which are engineered for high-reliability applications. The series is characterized by its compliance with automotive industry standards, specifically AEC-Q200. These devices offer a balance of performance and size, making them suitable for modern electronic systems where space is limited but robust protection is required.

Replacement Considerations

Direct substitutes must match the 10A hold current, 17A trip current, and 16V rating. Verify that alternative components also meet AEC-Q200 automotive qualifications. Ensure the replacement maintains the same radial leaded package dimensions for mechanical compatibility. Cross-reference datasheets for equivalent post-trip resistance values to maintain circuit efficiency.
