The Amphenol BERGSTIK® II 95687-448HLF is a 48-position, dual-row unshrouded male header on a 0.100" (2.54 mm) pitch with 0.100" row spacing. The 5 A per circuit rating is typical for signal-level duty on a standard 0.100" pitch header — the tin plating on both the mating and post sides keeps cost down for moderate mating-cycle applications.
The 0.100" (2.54 mm) pitch and 0.100" row spacing define the board footprint — 48 through-hole solder tails in two rows, each tail 0.360" (9.14 mm) long, with an overall contact length of 0.820" (20.83 mm). The 5 A per circuit is a per-contact limit at the rated voltage; for a 48-position header that means up to 240 A total across all pins, but the real limit is the temperature rise in the board and housing, so derate the current if you pack all circuits simultaneously. The tin plating (100.0 µin / 2.54 µm on the mating surface) is a workhorse finish — it handles a few dozen mating cycles in a clean environment, but if the board sees repeated field service or corrosive atmosphere, consider a gold-plated sibling in the BERGSTIK II family.
