Product details

Board-edge wiring with a friction lock

The 3-641127-3: This is a 3-position, single-row header from the MTA-100 series, designed for board-to-cable/wire applications.

Pitch, position, and plating check

The solder tails are tin-plated at 150.0µin (3.81µm), which is standard for wave-solder compatibility. The shrouded 1-wall design offers partial protection around the pins, reducing the chance of stubbing during blind mating. Insulation height is 0.225" (5.72mm) above the board surface. Operating temperature range is -55°C to 105°C, with a UL94 V-0 thermoplastic housing.
