MF-RHT400-0-14

Overview

The MF-RHT400-0-14 is a polymeric PTC resettable fuse from the Bourns MF-RHT series, designed for high-temperature applications. It features a hold current of 4 A and a maximum voltage rating of 16 V. The component has a typical resistance of 240 mΩ and can withstand a maximum trip current of 100 A. It operates within a temperature range of -40°C to +125°C and meets AEC-Q200 automotive qualification standards. The device utilizes radial leaded packaging with a lead spacing of 5.10 mm.

Feature Summary

Provides overcurrent protection through automatic reset functionality upon cooling after tripping.
Engineered for high-temperature environments with an operational limit up to 125°C.
Complies with AEC-Q200 automotive qualification requirements for reliability.

Applications

Automotive electronic circuit protection
High-temperature power supply input protection
Industrial control system overcurrent safeguarding

Procurement Notes

Verify the specific suffix '-14' against official Bourns documentation to confirm lead spacing and package dimensions. Ensure the selected variant matches the required hold current and voltage ratings for the target application. Confirm AEC-Q200 compliance status if automotive use is intended. Check for availability constraints as distribution may vary by region.

Selection Notes

Select this component when a 4 A hold current and 16 V maximum voltage are required in high-temperature environments. Consider the radial leaded form factor for through-hole PCB mounting. Evaluate the 240 mΩ resistance impact on circuit efficiency. Ensure the operating temperature range aligns with the system's thermal profile.

Part Context

This part belongs to the MF-RHT series of high-temperature PTC resettable fuses manufactured by Bourns Inc. The series is characterized by its ability to function reliably in demanding thermal conditions. The MF-RHT400-0-14 specifically denotes the 4 A hold current variant with radial leads and a 16 V rating.

Replacement Considerations

Consult official Bourns substitution guides for compatible alternatives. Verify that any substitute maintains the same hold current, voltage rating, and AEC-Q200 qualification. Ensure physical dimensions and lead spacing match the existing PCB layout.
