Samtec Inc. Header, 2.54Mm, Though Hole, Right Angle, 42 Position; Connector Systems Samtec TSW-121-22-G-D-RA

The Samtec Header, 2.54mm, Through Hole, Right Angle, 42 Position (part number 02R4021) is designed for board-to-board applications with a pitch spacing of 2.54mm. It features 42 contacts arranged in two rows, making it suitable for various electronic connections. 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 component 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 product is RoHS compliant and offers lead-free solderability options. Engineers should consider this header for applications requiring reliable connections in compact spaces, particularly where right-angle configurations are advantageous.
