0.100" Pitch, 4-Position Breakaway Header
The 5-146285-4: The breakaway design means the 4-position strip is part of a longer pin strip that can be snapped to length. For this order code, all 4 positions are loaded, so you get a fixed 4-pin header without extra break-off tabs. The 3 A rating is typical for signal-level loads on this pitch; the current is limited by the pin cross-section and the housing temperature rise, not the contact interface.
Gold Mating Finish for Repeated Connect Cycles
The mating surface carries 30 µinch gold over nickel. That plating grade supports 500+ mating cycles without significant wear, which matters if this header lives in a test fixture or a field-service panel where the connector gets disconnected and reconnected regularly.
Through-Hole Mount, Unshrouded Profile
Through-hole termination with a 0.090" (2.29mm) post length — the pins sit flush enough for single-sided boards but still give a solid solder fillet. Unshrouded means the pins are exposed after mating — no plastic shroud to guide or protect the receptacle.
