MF-USHT075KX/24-2

Overview

The Bourns MF-USHT075KX/24-2 is a high-temperature surface-mount PPTC resettable fuse from the Multifuse USHT series. It features a hold current of 750 mA and a trip current of 2.25 A, rated for a maximum voltage of 24 VDC. The device offers a maximum fault current rating of 20 A with an initial resistance of 680 mOhms. Housed in a 1210 (3225 metric) package measuring 3.2 x 2.5 mm, it operates within a temperature range of -40°C to +125°C.

Feature Summary

High-temperature polymer construction designed for elevated thermal environments
Surface-mount SMD/SMT termination for automated PCB assembly
AEC-Q200 automotive qualification ensuring reliability under harsh conditions

Applications

Automotive electronic circuit protection
High-temperature industrial control systems
Consumer electronics requiring compact overcurrent safeguards

Procurement Notes

Verify that the specific suffix 'KX/24-2' matches the required voltage and temperature ratings for your design. Confirm RoHS compliance status via the official datasheet before finalizing component selection. Ensure the 1210 footprint aligns with your PCB layout constraints.

Selection Notes

Select this component when standard PPTC fuses fail to withstand operating temperatures above 85°C. The 24V rating suits low-voltage DC lines. Compare against the MF-PSMF series if lower temperature operation is acceptable, as the USHT series provides superior thermal resilience at the cost of higher initial resistance.

Part Context

This part belongs to the Bourns Multifuse USHT series, specialized for high-temperature applications. Unlike the standard MF-PSMF or MF-MSMF series, the USHT line utilizes materials capable of maintaining performance up to 125°C. It serves as a robust alternative for automotive and industrial sectors where ambient heat exceeds typical consumer electronics limits.
