Overview

The 91901-31125LF is a 25-position vertical board-to-board header from the CONAN series, designed for high-density mezzanine connections. It features a 1.0mm pitch and surface mount termination with solder retention features for secure mechanical attachment to the PCB. This connector utilizes GXT plating (palladium-nickel with gold flash) to provide high durability and reliable electrical performance in a compact 0.86mm profile height.

Why Choose This Part

This header offers a very low profile height of 0.86mm above the board, enabling slim product designs. The use of GXT plating provides superior wear resistance compared to standard gold plating, ensuring long-term contact integrity. Additionally, the inclusion of solder retention features improves the mechanical stability of the SMT joints during assembly and use.

Applications

Mezzanine Board Stacking
Used to connect daughter cards to motherboards in space-constrained industrial or networking equipment.
Embedded Computing Modules
Ideal for interconnecting COM (Computer-On-Module) boards where a reliable 1.0mm pitch interface is required.
Industrial Automation Controllers
Provides a robust board-to-board link for internal sensor processing boards and communication modules.
Telecommunications Hardware
Serves as a high-density signal interface for line cards and backplane management controllers.
