The Amphenol 10033527-N3212LF is a USB mini AB receptacle — the 5-contact, USB 2.0-rated version of the 10033527 series. It accepts either a mini A or mini B plug, which makes it the single-port solution for devices that need to support both host and peripheral connections from the same jack, common on portable instruments and data-logging gear.
Mating Cycles and Contact Plating
Rated for 5000 mating cycles, this receptacle carries gold-plated contacts that handle repeated connect-disconnect duty in field-service or test equipment without fretting corrosion. The gold finish also resists oxidation in humid or lightly corrosive environments, extending reliable contact life beyond what a tin-plated USB jack would deliver at this cycle count.
Board Mounting and Retention
The board guide aligns the connector during pick-and-place, and the solder retention tabs anchor the shield to the PCB pads, taking strain off the signal pins during cable insertion and removal. The shielded copper alloy shell provides EMI containment for the USB 2.0 differential pair.
