Sockets 1. DESCRIPTION OF CONNECTOR AND INTENDED APPLICATION A range of round pin and wire-wrap I.C. sockets intended to accommodate integrated circuits and other components having connection pins. Machined female contacts with gold-plated contact finish are housed in glass-filled thermoplastic housings. Termination surfaces are tin-plated throughboard solder and wire-wrap terminations. Single row modular and double row styles are available. 2. RATINGS 2.1.
