2.54mm Pitch Dual-row Female Header (Straight/Vertical Through-hole, High-temperature resistant, Board-to-Board Connector)
1. General Description
This component is a 2.54mm pitch (0.1-inch pitch) dual-row female header connector, designed for board-to-board (BTB) connections in high-reliability electronic applications. It features:
-
Through-hole (THT) mounting for secure PCB soldering.
-
High-temperature resistance (typically rated for >105°C, with some models supporting 125°C or higher).
-
Standard 2.54mm pin spacing, compatible with male pin headers (e.g., 2×2P to 2×40P).
