The 70AAJ-4-F0G is a surface-mount modular female contact connector designed for stackable interconnect applications. It features a 2.54 mm pitch and height with 2 to 6 precious metal contacts, offering a symmetrical pad layout with twin hot contacts for reliable electrical connection. The connector is rated for 3 A per contact at 60 V with a maximum contact resistance of 30 mO, dielectric voltage of AC 500 V, and insulating resistance of 1000 MO minimum. Operating over a temperature range of -55°C to 125°C with a minimum durability of 50,000 cycles, the contact resistance remains at 50 mO after 50,000 cycles. The insulator is constructed from glass-reinforced thermoplastic (UL 94V-0 rated), with copper alloy contacts finished in 30 µ" minimum nickel underplating and 30 µ" minimum gold over nickel contact area. This RoHS-compliant and halogen-free connector is ideal for pick-and-place compatible applications requiring high cycle life and reliable modular stacking in industrial and consumer electronics.
