Product details

What this MTA-100 header is for

The 3-641126-4: This is a 4-position, single-row, shrouded header from the MTA-100 series, designed for board-to-cable/wire connections. The 0.100" (2.54mm) pitch matches standard IDC receptacles and crimp housings in the MTA-100 family.

Mating contacts are gold-plated to 15.0µin (0.38µm), which resists corrosion and maintains low contact resistance over repeated mate/unmate cycles. The post tails are tin-plated to 150.0µin (3.81µm) for reliable solder wetting during through-hole assembly.
