Product details

Why the 11-Pin Count Matters in a Single-Row Header

The 77311-801-11LF is an 11-position, single-row BERGSTIK header from Amphenol ICC (FCI). The odd pin count is deliberate — it fits BOM positions that call for exactly 11 circuits without the wasted board area of a dual-row footprint.

Contact Plating and Current Rating — Signal Duty, Not Power Bus

At 3 A per pin in an 11-position header, the total current through the connector is 33 A if all pins are loaded simultaneously — but the derating curve (not provided here) would reduce that at elevated ambient temperatures.

Frequently asked questions

Where can I buy 77311-801-11LF and what is the price?

No stock-holding claim is made — each order is sourced per the buyer's quantity and delivery requirements.

What is the pitch of 77311-801-11LF?

The mating pitch is 0.100" (2.54 mm), which is the standard spacing for BERGSTIK headers and compatible with most 0.100" pitch socket strips and IDC receptacles.
