All 54 positions are loaded with square male pins in phosphor bronze, with the mating surface finished in 30.0µin (0.76µm) gold or GXT™ — a plating grade that supports repeated mating cycles in a production environment without contact fretting. The through-hole solder termination and 0.200" (5.08mm) post length suit standard PCB thicknesses, while the 0.100" (2.54mm) insulation height keeps the mated stack-up low.
The 79821-154HLF is a 54-position, dual-row header with all positions loaded. It uses a 0.100" (2.54mm) pitch in both rows and between rows, with square male pins.
The 79821-154HLF is listed with RoHS compliance as part of the BERGSTIK® II series. Confirm the specific compliance certificate with your order.
