If your board sits near a hot component or in a sealed enclosure, derate the current per the standard AMPMODU derating curve — the 3 A ceiling assumes free convection at room temperature. Through-hole solder termination — no press-fit, no surface-mount. The unshrouded header gives you access to each pin for probing or rework, but offers no polarization — double-check the mating orientation before wave solder. The base product number is 146277; the -4 suffix specifies the 4-position variant. Bulk packaging — no tape-and-reel, so plan for hand placement or tube feed if your assembly line expects reeled parts.","metaTitle":"5-146277-4 TE AMPMODU Mod II Header, 4-Pos, 0.100\" Pitch","metaDescription":"5-146277-4 TE Connectivity AMPMODU Mod II breakaway header, 4 positions, 0.100\" pitch, gold mating, 3 A.
