The 70AAJ-2-F0G is a surface-mount modular female contact connector manufactured by Bourns, designed for high-reliability interconnection applications. It features a 2.54 mm pitch and height with 2 to 6 precious metal contacts, end-to-end stackability, and a symmetrical pad layout with twin hot contacts for pick-and-place compatibility. The contact area is finished with 30 µ" minimum gold over nickel underplating, and the glass-reinforced thermoplastic insulator is UL 94V-0 rated and halogen-free. Operating specifications include a 3 A current rating per contact, 60 V voltage rating, maximum contact resistance of 30 mO, and a wide operating temperature range of -55°C to 125°C with a minimum durability of 50,000 cycles. This connector is ideal for modular, stackable interconnect systems in industrial, telecommunications, and consumer electronics applications where reliability and compact form factor are essential.
