MF-RHT100-AP

Overview

The Bourns MF-RHT100-AP is a radial leaded polymer positive temperature coefficient (PPTC) resettable fuse from the Multifuse RHT series. Designed for high-temperature environments, it features a maximum operating temperature of +125°C and a rated voltage of 30V. The device maintains a hold current of 1.0A with a typical resistance of 180 milliohms. It is AEC-Q200 qualified for automotive reliability and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides overcurrent protection through automatic trip and reset functionality without manual intervention
• Engineered with a specialized polymer PTC element capable of robust performance in high-voltage and high-temperature conditions
• Eliminates nuisance tripping caused by ambient temperature fluctuations while maintaining circuit integrity

Applications

• Automotive electronic circuit protection
• High-reliability industrial equipment overcurrent safeguarding
• Consumer electronics surge and short-circuit protection

Procurement Notes

Verify that the specific suffix 'AP' matches the required packaging configuration, as ordering suffixes may indicate variations in bulk quantity or tape-and-reel specifications rather than electrical changes. Confirm AEC-Q200 qualification status is required for the target application. Ensure the radial leaded package style aligns with the printed circuit board layout constraints before finalizing the procurement order.

Selection Notes

Select this component when the design requires a 1.0A hold current and a 30V maximum rating. The choice is driven by the need for high-temperature stability up to 125°C and compliance with automotive quality standards. Engineers should evaluate the 180 milliohm resistance against power dissipation limits and ensure the radial leaded form factor fits the assembly process.

Part Context

This part belongs to the Bourns Multifuse RHT series, which utilizes advanced polymer technology for resettable fuses. The series is specifically engineered to address the challenges of harsh operating environments, offering a cost-effective alternative to traditional fusible links. The radial leaded construction provides mechanical stability for through-hole mounting applications.

Replacement Considerations

Consult official Bourns substitution guides for direct replacements. Verify that any substitute maintains the 1.0A hold current, 30V rating, and AEC-Q200 qualification to ensure equivalent performance in high-temperature automotive or industrial circuits.
