Why a 4-Position Breakaway Saves a Board Spin
Sizing the Current and Temperature Envelope
The 3 A per contact rating is at 25 °C ambient. 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.
