Board-to-Board Workhorse: 46-Position Unshrouded Header
The 0.100" (2.54 mm) pitch and 0.100" row spacing match decades of legacy footprint layouts, so any board designed for this pitch accepts the header without a layout change. Rated 5 A per circuit with 30.0 µin gold on the mating interface, the contacts handle moderate power or repeated signal-level mating cycles without fretting.
The 46 positions are fully loaded. The 5 A per-contact rating is the current each pin can carry before the temperature rise hits the UL94 V-0 housing limit.
