MF-RHT070-0

Overview

The Bourns MF-RHT070-0 is a radial leaded polymer positive temperature coefficient (PPTC) resettable fuse designed for high-temperature circuit protection. It features a hold current of 0.7A and a trip current of 1.4A, operating within a voltage range up to 16V. The device offers a maximum interrupt rating of 40A and maintains a resistance between 0.3Ω and 800mΩ. It functions reliably across an operating temperature range of -40°C to +125°C, providing robust overcurrent protection in demanding environments.

Feature Summary

• Utilizes polymer PTC technology for automatic reset after fault clearance
• Engineered for high-temperature stability up to 125°C
• Radial leaded package facilitates through-hole PCB mounting

Applications

• Automotive circuit protection
• High-reliability electronic equipment
• Industrial transportation systems
• Communication infrastructure
• Consumer electronics surge protection

Procurement Notes

Verify the specific voltage rating requirements against the datasheet, as this component is rated for 16V. Confirm that the radial lead spacing matches the target PCB footprint. Ensure the application environment does not exceed the 125°C maximum operating temperature limit. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a radial leaded form factor is required for high-temperature applications. The 0.7A hold current suits circuits needing moderate overcurrent protection. Consider the 16V voltage rating for low-voltage DC systems. Evaluate the 40A max current capability for short-circuit scenarios.

Part Context

This part belongs to the Multifuse RHT series, which specializes in high-temperature PPTC devices. The series is designed to eliminate tripping caused by ambient temperature variations while providing cost-effective protection in compact packages.

Replacement Considerations

MF-RHT070-2-17 is a confirmed substitute with similar electrical characteristics but a higher voltage rating of 30V.
