Save space with shrinking USB connectors
The new series of mini-BTM USB connectors from Molex take up only about 1/8th of the space of standard USB-B connectors.
Power connectors meet SSI specifications
The new DPS/MPS power connectors from Molex meet the Server System Infrastructure (SSI) open specifications for backplanes.
The microSD format offers about a 70% space saving compared to the miniSD.
"Having a connector that will hold these miniature memory card connectors securely in place, while also providing smooth card extraction, is a key consideration of mobile device makers", says Bill Kysiak, of Molex.
"These new connectors address these concerns while offering additional space savings to help allow for thinner, smaller, portable designs".
Molex offers normal and reverse-mount style microSD connectors in a push-push design that enables easy external card extraction from the side of a mobile device.
These styles include brake tabs to help slow the speed of the card during ejection.
Additional features include a detect switch to identify card insertion and inner or outer solder tabs to suit various design needs.
The smallest of these versions offers a height of 1.80mm (.071in) and a depth of 15.50mm (.610in), making it among the smallest memory card connectors in the world.
These push-push versions include four PCB ground tabs for secure board retention and polarisation features to ensure correct card insertion.
A hinge-type version is also offered for cards mounted inside the unit, enabling the card to be inserted from the top angle.
Molex's novel hinge design holds the card in the metal lid and includes a spring function to enable easy card extraction.
The durable metal lid stays securely fastened to the connector even after multiple cycles, and provides an audible click and positive lock to ensure good electrical contact.
The shell has no sharp edges or corners to ensure safe usage and includes probe holes for electrical testing.
Molex's full range of microSD card connectors are rated at 0.5A and include metal shielding for ESD protection.
These eight-circuit connectors include gold-plated terminals and high-temperature housings, and come in embossed tape packaging for robotic pick and place.
When used with adapters, they are fully compatible with systems that support SD and miniSD.
