It's a through-hole solder type with square male pins, push-pull mating, and a black UL94 V-0 rated insulator. Typical use is as a board-to-board interconnect — think signal or low-current power links between PCBs where you need a simple, reliable pin header. The 0.100\" (2.54 mm) pitch is the classic breadboard and perfboard spacing — any board layout engineer will recognize the footprint immediately. 4 positions in 2 rows means a 2x2 grid; the row spacing is also 0.100\" (2.54 mm), so the pin pattern is a clean square. That's the real limit — the tin surface, not the current rating, governs where this part belongs.","metaTitle":"79821-404HLF BERGSTIK II Header, 4 Pos, 2.54mm Pitch, 5A","metaDescription":"Amphenol FCI 79821-404HLF BERGSTIK II dual-row header, 4 positions, 0.100\" pitch, 5A, tin-plated, through-hole.
