MF-NSHT035KX-2 Description

Short technical summary and product information.

The Bourns MF-NSHT035KX-2 is a polymeric PTC resettable fuse from the MF-NSHT series, designed for overcurrent protection in space-constrained applications. It features a maximum voltage rating of 30V and a maximum current rating of 20A. The hold current is 350mA, with a trip current of 1.75A. Initial resistance is 0.40Ω, and post-trip resistance is 2.6Ω maximum. Trip time is 100ms at 8A and 23°C, with a tripped power dissipation of 0.9W.

 

This device is housed in a 1206 (3216 Metric) concave surface mount package, measuring 3.20mm x 1.60mm with a maximum thickness of 0.85mm. It operates over a wide temperature range of -40°C to 125°C, making it suitable for harsh environments. The fuse is AEC-Q200 qualified, ensuring reliability for automotive applications.

 

Typical applications include overcurrent protection in automotive electronics, battery management systems, industrial controls, and portable devices where resettable protection is preferred over one-time fuses. The low resistance helps minimize power loss during normal operation.
