The Header, 2.54mm, Through Hole Vertical, 84 Position (part number 12P3790) from Samtec is designed for board-to-board applications with a pitch spacing of 2.54mm. It features 84 contacts arranged in 2 rows, making it suitable for various connectivity needs. The header is constructed with a black glass-filled polyester insulator and utilizes phosphor bronze for the terminals, which can be plated with either gold or tin over nickel. This product operates within a temperature range of -55 ¬8C to +125 ¬8C when gold-plated, and -55 ¬8C to +105 ¬8C with tin plating. The voltage ratings vary depending on the mating connector, with a maximum of 550 VAC when mated with SSW connectors. The current rating per pin varies based on the mating connector type, with values ranging from 4.3 A to 6.3 A. The header is RoHS compliant and offers lead-free solderable options. Engineers should consider this header for applications requiring reliable and robust connections in environments with varying temperature conditions.
