MF-MSMF014-2 Description

Short technical summary and product information.

The Bourns MF-MSMF014-2 is a polymeric PTC resettable fuse from the MF-MSMF series, designed for overcurrent protection in a wide range of applications. It is rated for a maximum voltage of 60V and a hold current of 140mA at 23°C, with a trip current of 0.34A. The device can handle a maximum fault current of 40A and features a low resistance range of 0.4Ω (minimum) to 6.5Ω (maximum) at 23°C. The typical time to trip is 150ms at 1.5A, and the tripped power dissipation is 0.8W.

 

The fuse is AEC-Q200 qualified, making it suitable for automotive electronics, and carries cUL and TÜV agency approvals. It is RoHS3 compliant and halogen free. The operating temperature range is -40°C to 85°C.

 

The MF-MSMF014-2 is housed in a 1812 (4532 Metric) concave surface mount package with dimensions of 4.55mm length, 3.24mm width, and 1.10mm maximum thickness. It is designed for automated assembly and is compatible with lead-free solder reflow profiles.
