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, occupying minimal space on the PCB. The MI21 Series includes ground terminals for enhanced connectivity. A reliable two-point ejection mechanism ensures even card ejection. Designed for automatic mounting equipment, both headers and receptacles have features to accommodate pick-and-place nozzles and are suitable for top-of-board mounting. Available in rich variations, these connectors support Type I and Type I/II CompactFlash cards and offer options for eject button position, standoff height, and board mounting style. They are compliant with Compact Flash Association standards and are suitable for applications such as PDAs and digital still cameras.
