SIM/microSD Combo Connectors Offer PCB Space Savings

Flaunting the smallest overall dimensions of any similar combo version currently on the market, the company’s microSD/SIM card combo connector combines two memory card functions in one form factor to free up PCB space. The connector includes a reverse-mount, eight-circuit microSD slot and options for a six- or eight-circuit normal-mount SIM card slot. With a mounted height of 2.75 mm and a width and depth of 17.7 mm, visible solder tails are located on two sides of the connector for easy mounting and inspection while still providing coplanarity control of a maximum of 0.1 mm after reflow soldering. The microSD portion includes a push-push eject function for insertion and withdrawal of the cards and the slightly larger SIM card area utilizes an economical push-pull eject method. Features include a detect switch, which identifies card insertion and also provides a wiping function for reliable electrical contact, and a card-polarization feature that prevents improper card insertion, and a lifespan up to 7,000 mating/unmating cycles. The connector is rated at 0.5A and 100V for microSD and 5V for SIM. MOLEX INC., Lisle, IL. (800) 786-6539.
