MF-FSMF035X-2 Description

Short technical summary and product information.

The Bourns MF-FSMF035X-2 is a polymeric PTC resettable fuse from the MF-FSMF series. It is designed for overcurrent protection in compact electronic circuits. Key electrical specifications include a maximum voltage of 6V, a hold current of 350mA, a trip current of 750mA, and a maximum interrupt current of 40A. The device features a fast time to trip of 100ms at 8A, with an initial resistance of 0.2Ω and a post-trip resistance of 1.4Ω. Typical tripped power dissipation is 0.5W.

 

This fuse is housed in a 0603 (1608 metric) surface mount package with dimensions 1.65mm x 0.85mm and a maximum thickness of 0.65mm. It operates over a temperature range of -40°C to 85°C. The MF-FSMF035X-2 is RoHS compliant, halogen free, and has an MSL rating of Level 1. It is suitable for applications such as USB port protection, HDMI 1.4 source protection, PC motherboard plug and play protection, and battery/port protection in mobile devices, PDAs, and digital cameras.
