Product details

The Amphenol FCI 79821-420HLF is a 20-position, dual-row unshrouded header from the BERGSTIK® II series, on the standard 0.100" (2.54mm) pitch.

The dual-row arrangement with 0.100" (2.54mm) row spacing means the 20 pins occupy a 10-position-wide footprint per row. The overall contact length of 0.730" (18.54mm) splits into a 0.430" (10.92mm) mating length and a 0.200" (5.08mm) solder tail — the post length is what determines the board thickness and through-hole barrel depth.

5 A per circuit is the rated current.

Frequently asked questions

What is the mating connector for the 79821-420HLF?

This unshrouded header mates with any standard 0.100" (2.54mm) pitch dual-row receptacle, typically a BERGSTIK II socket or a generic IDC socket with matching pitch and row count.
