DF3E-4P-2V(54)

Headers, Male Pins Overview

The DF3E-4P-2V(54) is a shrouded header connector from the Hirose DF3 series, designed for surface mount (SMD/SMT) applications. It features a 2 mm pitch and provides 4 positions in a single row configuration. The component utilizes male pin contacts made of brass with gold plating to ensure reliable signal transmission. Rated for 3 A current and 250 V voltage, it operates within a temperature range of -55°C to +105°C. The housing is constructed from beige polyamide (PA) plastic with a UL 94 V-0 flammability rating.
