Product details

40-Pin SMT Breakaway Header for Board-to-Board Stacking

The 95278-408-40LF: This is a 40-position, dual-row BERGSTIK® unshrouded header from Amphenol ICC (FCI), designed for board-to-board stacking where the mating receptacle sits on a parallel PCB. The surface-mount solder tails reflow onto the board pads; no through-hole means the opposite side stays clear for routing. The breakaway construction lets you snap the strip to a shorter length if the BOM calls for fewer positions — all 40 are loaded here.

Tin Contacts and Wide Temperature Range

The 3 A per-contact rating holds up to the temperature rise limit of the housing. The operating range of -65°C to 125°C covers most industrial and automotive underhood environments.
