Product details

The 77313-118-48LF: The through-hole solder tails measure 0.120" (3.05mm) long, enough to clear a 1.6mm board and still leave a visible fillet on the solder side. The 0.100" row spacing matches the pitch, so the pad pattern is a simple 2×24 grid. Board layout engineers can route one trace between pads on a standard 1 oz copper layer without necking down below 0.008" trace width.

Mating contacts are plated with gold or GXT™ over 30.0µinch (0.76µm) of nickel underplate. The solder tails are tin-plated (78.7µinch / 2.00µm), which wets well in lead-free wave or hand-solder processes. No need for a separate gold-flash step on the post.

Peer Comparison in the BERGSTIK® Line

The 77313-118-48LF sits alongside siblings 77313-118-26LF (26 positions) and 77313-118-16LF (16 positions) in the same dual-row, unshrouded, 0.100" pitch format.

Frequently asked questions

What is the pin pitch of 77313-118-48LF?

The mating pitch is 0.100" (2.54mm), with the same 0.100" row spacing between the two rows. This is the standard 0.100" grid used across the BERGSTIK® series.

Is 77313-118-48LF a shrouded or unshrouded header?

It is unshrouded — a breakaway header with no plastic shroud around the pins. The fastening type is push-pull, meaning the mating receptacle relies on friction fit without a locking latch.
