MF-PSMF050X-2 Description

Short technical summary and product information.

The Bourns MF-PSMF050X-2 is a polymeric PTC resettable fuse designed for overcurrent protection in compact electronic circuits. It is rated for a maximum voltage of 6V and a hold current of 500mA, with a trip current of 1.00A at 23°C. The device offers a low initial resistance of 0.15Ω and a maximum post-trip resistance of 0.9Ω, ensuring minimal power dissipation under normal operation.

 

This resettable fuse is housed in an 0805 (2012 Metric) concave surface mount package with dimensions 2.15mm x 1.35mm and a maximum thickness of 0.85mm. It operates over a temperature range of -40°C to +85°C and has a typical time to trip of 100ms at 8.0A. The component is suitable for USB port protection, HDMI source protection, and other applications requiring fast response to fault events.

 

The MF-PSMF050X-2 is RoHS compliant and halogen free, with agency approvals from cUL and TÜV. It is designed for surface mount assembly and is compatible with standard reflow soldering processes.
