MF-RHT200-AP

Overview

The Bourns MF-RHT200-AP is a radial leaded PTC resettable fuse from the Multifuse MF-RHT series, designed for high-temperature circuit protection. It features a 2 A holding current and a 3.8 A trip current, operating at a maximum voltage of 16 VDC. The device has an initial resistance of 45 mOhms and a post-trip resistance up to 110 mOhms. It withstands fault currents up to 100 A and dissipates 1.4 W of power. Operating within a -40°C to +125°C range, it measures 9.4 mm in diameter and 3 mm in height with a 5.1 mm lead spacing.

Feature Summary

• Provides overcurrent surge protection for electronic equipment in high operating temperature ranges
• Automotive-grade reliability certified under AEC-Q200 standards
• Radial leaded construction facilitates through-hole PCB mounting

Applications

• Overcurrent protection in automotive electronics
• Circuit protection for high-temperature industrial applications
• Surge protection for portable electronic devices

Procurement Notes

Verify that the suffix AP corresponds to the specific packaging configuration required for your assembly line. Confirm the AEC-Q200 qualification status aligns with your automotive or industrial design specifications. Ensure the 16 VDC rating meets the system's maximum voltage requirements before finalizing procurement orders.

Selection Notes

Select this component when a 2 A hold current and 16 VDC rating are required for high-temperature environments. The radial leaded package suits through-hole PCB designs where space allows for 9.4 mm diameter clearance. Consider the 100 A max fault current capability for robust short-circuit protection needs.

Part Context

This part belongs to the Bourns Multifuse MF-RHT series, specialized for high-temperature applications. It complements other variants like the MF-RHT200-2 and MF-RHT200/32-AP within the same family, offering consistent PTC technology adapted for different voltage ratings and packaging options.

Replacement Considerations

The MF-RHT200-2 serves as a direct functional substitute with identical electrical parameters but may differ in packaging suffix. Verify lead spacing and dimensional compatibility before substitution.
