The Amphenol 86837-410HLF is a 10-position, dual-row unshrouded header from the BERGSTIK® II series, designed for board-to-board interconnect applications. It uses a standard 0.100" (2.54mm) pitch on both rows and between rows, making it footprint-compatible with a wide range of legacy and current designs. The male square pins are through-hole soldered, with tin plating on both the mating surface and the solder tails.
Key Ratings and What They Mean
Rated 5A per contact, the 86837-410HLF is suited for signal-level and moderate power distribution on a PCB — the limiting factor is the temperature rise through the unshrouded body, not the phosphor bronze contact itself. The 110V voltage rating provides adequate margin for typical logic-level and low-voltage power rails. The tin-on-tin contact interface is cost-effective for applications with limited mating cycles (typically under 50 cycles); for higher durability or corrosive environments, a gold-plated variant in the same series would be the better choice.
Construction and Compliance
The housing is molded in black UL94 V-0 rated thermoplastic, meeting the flammability requirement for equipment inside an enclosure. The push-pull fastening type means the header relies on friction from the mating receptacle for retention — no locking latch, so it is best suited for internal connections where the mated pair will not be subject to vibration or cable strain. The 0.100" (2.54mm) insulation height keeps the profile low on the board.
