The USB 3.0 type-C reversible connector ready for production

The USB 3.0 promoter group this week announced the completion of the USB type-C specification that defines the next generation USB connector. The new plug is reversible and is considerably thinner than existing ones. Moreover, it will support up to 10Gb/s transfer rates as well as up to 100W power delivery.

The USB type-C connector is the latest evolution of the USB. Both the connector and the receptacle (which is 8.4mm*2.6mm in size) are reversible, more durable than the current ones (they are guaranteed to sustain up to 10K cycles) and feature improved EMI- and RFI-mitigation features. The USB type-C standard is compatible with all USB protocols, but since the new connectors and receptacles are not physically compatible with other USB connectors and receptacles, special passive adapters will be introduced. The release of the USB type C specification is the final piece in developing a single-cable solution for different kinds of devices.


As expected, the new USB 3.1 type C will support up to 10Gb/s transfer rates as well as ability to deliver up to 100W of power to devices. The connector, cable and receptacle support scalable power charging. In addition, the USB 3.1 type C connector design will scale for future USB bus data rates.

The USB 3.1 type-C connector will be used for PCs, mobile (smartphones, tablets, etc.), automotive, consumer (cameras) and IoT applications.


“Interest in the USB Type-C connector has not only been global, but cross-industry as well,” said Brad Saunders, USB 3.0 promoter group chairman. “Representatives from the PC, mobile, automotive and IoT industries have been knocking down our door anticipating this new standard. This specification is the culmination of an extensive, cooperative effort among industry leaders to standardize the next generation USB connector as a long-lasting, robust solution.”

It is expected that the first applications with USB 3.1 type-C connector will emerge on the market before the end of the year.

KitGuru Says: The USB Type-C connector is just what the doctor ordered for the universal serial bus standard. The new USB connector can be plugged-in easily, just like FireWire/IEEE1394, Lightning or any other consumer electronics connectors without concerns regarding orientation. Moreover, the USB 3.1 supports up to 10Gb/s data-rates, which should be enough for almost any type of consumer device in the foreseeable future.
