Product details

The FCI / BergStik® II 79821-456HLF is a 56-position, dual-row, unshrouded male pin header on a standard 0.100" (2.54mm) pitch.

For a 56-position dual-row header, that means the total current through the connector can add up, but the per-contact limit keeps the overall temperature rise under control. The 110 V rating is the working voltage; it's the creepage distance over the unshrouded header that sets that ceiling, so keep the board clean and conformally coat if running near the limit in humid environments.

Frequently asked questions

What is the current rating of the BergStik II header 79821-456HLF?

It is rated 5 A per contact. The per-contact limit keeps the temperature rise within the UL94 V-0 housing's capability.
