MF-RG1000-AP

Overview

The Bourns MF-RG1000-AP is a Multifuse polymer positive temperature coefficient (PPTC) resettable fuse designed for overcurrent protection in electronic circuits. This component belongs to the RG series, which utilizes advanced polymer PTC technology to provide robust circuit safeguarding against short circuits and excessive current conditions. The device operates by increasing resistance significantly when heated above its trip threshold, thereby limiting current flow. Upon cooling, it returns to its low-resistance state, allowing the circuit to resume normal operation without manual replacement. It is engineered for high reliability in demanding environments.

Feature Summary

• Polymer positive temperature coefficient technology for automatic reset functionality
• High reliability construction suitable for harsh operating conditions
• Compact surface mount design facilitating automated assembly

Applications

• Overcurrent protection for portable electronic devices
• Circuit safeguarding in telecommunications equipment
• Protection for automotive electronics applications

Procurement Notes

Verify the specific hold current and trip current ratings required for your application against the official datasheet specifications. Confirm that the voltage rating aligns with your system's operational parameters. Ensure the package type matches your PCB layout requirements. Check for any recent updates to the RoHS compliance status or material declarations before finalizing procurement orders.

Selection Notes

Select this component based on the maximum operating voltage and continuous current requirements of your circuit. Consider the ambient temperature range, as PPTC performance is temperature-dependent. Evaluate the time-to-trip characteristics to ensure adequate protection speed for sensitive downstream components. Verify compatibility with reflow soldering profiles if using surface mount variants.

Part Context

This part is part of Bourns' Multifuse family of resettable fuses, offering an alternative to traditional one-time fuses. The RG series specifically targets applications requiring reliable, space-saving protection solutions. Bourns manufactures these components in facilities certified to industry standards, ensuring consistent quality and performance across production batches.

Replacement Considerations

When replacing, ensure the substitute part meets or exceeds the original voltage, current, and physical dimensions. Verify that the new component's trip characteristics match the system's protection requirements. Check for equivalent certifications and compliance standards.
