MOLEX's 67840 series of SMT Secure Digital/Secure Digital IO (SD/SDIO) memory card connectors maximise space saving.
This new series of connectors features 1.8mm stand-offs for good solderability and even allows a 1.5mm high ASIC chip to be mounted beneath the connector.
Offered in top mount styles with a maximum terminal-and-nail co-planarity of 0.1mm, the memory card connector assemblies are available in two footprint versions to fit custom PCB requirements.
One of the two versions features separate metal solder-tabs built under each arm extension of the connector housing. The single-piece metal shell of the connector has four metal tabs to provide robust connector securement to PCB as well as for I/O grounding.
The other version features I/O grounding metal tabs located mid-way of connector edge. Both versions have locating pegs which are part of the housing design.
These 9-circuit connectors have a low profile height of 2.80mm and accept industry standard SD memory cards.
The connectors have metal grounding covers for EMI/RFI protection and feature a unique "push-push" eject system for card insertion/extraction and secure card retention.
Other features include beveled spring contacts for secure mating retention and an off-set terminal for first-make/last-break capabilities.
The connectors are rated at 0.5A per contact and can withstand up to 10,000 cycles. Their detect-and-write-protect switch functions enable secure downloading of digital data such as image and MPEG-video files.
The connectors are available in embossed tape packaging for automatic board mounting.
