Overview

The ST4-40-1.00-L-D-P-TR is a high-density, 80-position board-to-board connector header featuring an ultra-fine 0.40mm pitch. Designed for vertical surface mount applications, this center strip contact header includes a locking latch mechanism and a pick-and-place pad for automated assembly. It supports mated stacking heights of 4mm and 4.5mm, making it ideal for compact, low-profile electronic designs.

Why Choose This Part

The connector features 10 micro-inches of selective gold plating for reliable electrical contact and a locking latch system for increased mechanical stability in high-vibration environments. Its low 3.07mm height above the board allows for extremely slim device profiles, and the integrated pick-and-place pad facilitates high-speed SMT manufacturing.

Applications

High-Density Mezzanine Cards
Used for interconnecting parallel printed circuit boards in space-constrained mobile or handheld devices.
Module-to-Baseboard Connections
Ideal for connecting processor modules or wireless communication cards to a carrier board with a secure latching interface.
High-Speed Signal Distribution
Suitable for signal routing where a 0.40mm pitch is required to maintain a small PCB footprint while providing 80 total pins.
