The MI20/21 Series Compact Flash Card Connectors are designed for miniaturization and efficient board placement. These connectors feature a compact design with small width and depth, minimizing board footprint. The MI21 Series includes ground terminals, and both series utilize a two-point ejection mechanism for reliable card ejection. Designed for automatic mounting, headers have a pick-up area for placement nozzles, while receptacles are top-board mountable. Available in rich variations, these connectors support Type I and Type I/II cards and offer options for eject button position, standoff height, and board mounting style. They are suitable for applications such as PDAs and digital still cameras, complying with Compact Flash Association standards.
