40-Position Unshrouded Header at 0.100" Pitch
The 77313-802-40LF: The breakaway design lets you snap the strip to a shorter length if the BOM calls for fewer circuits, but this order code ships fully loaded at 40 positions. The through-hole solder tails are tin-plated (78.7 µinch) for good solder wetting, and the post length of 0.135" (3.43 mm) suits standard PCB thicknesses.
Mounts vertically through-hole, unshrouded, with a push-pull fastening — no locking latch, so in high-vibration environments you'll want to pair it with a receptacle that has a friction lock or use a secondary retention method like a glue dot or wire tie. Operating temperature range is -65°C to 130°C, covering automotive underhood and industrial cabinet duty.
