The 57102-F06-23LF: This 46-position dual-row unshrouded header from the Minitek 2.00mm series carries 2A per contact at 200V AC/DC. The 2.00mm pitch sets the board routing density — at 46 circuits, the footprint spans roughly 46 mm across the rows, demanding careful trace fan-out on the PCB.
Gold Flash Mating — Corrosion Protection for Moderate-Cycle Duty
The mating contacts carry a gold flash finish over copper alloy. Gold flash provides a low-resistance, corrosion-resistant interface for periodic mating — think field-serviceable boards or test headers where the connector sees dozens to low hundreds of cycles. For applications requiring thousands of mating cycles, a thicker gold plate (e.g., 30 µinch) would be specified instead.
Through-Hole Solder Termination — Mechanical Retention for Cable Strain
In a board-to-board stack where the header sees shear forces from the mating cable or daughtercard, the through-hole joints distribute stress better than surface-mount.
