Samtec Inc. Header, 2.54Mm, Though Hole Vertical, 120 Position; Connector Systems Samtec HTSW-140-23-G-T

The Header, 2.54mm, Through Hole Vertical, 120 Position (part number 83T9960) from Samtec is designed for board-to-board applications with a pitch spacing of 2.54mm. It features three rows and a total of 120 contacts, suitable for various configurations. 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, with values ranging from 4.3 A to 6.3 A. The header is RoHS compliant and lead-free solderable, making it suitable for modern electronic applications. Engineers should consider this header for projects requiring reliable connectivity in compact spaces, especially where high-density pin configurations are necessary.
