What is a Micro USB Connector?

The Micro USB is a popular and versatile I/O connector and is currently the smallest form factor available in the USB range, almost 40% smaller than a USB Type C equivalent.

Micro USB connectors are made up of five contacts, with its tiny form factor enabling manufacturers to produce slimmer and more compact devices. Rated to 10,000 mating cycles as standard, it is a very attractive proposition when considering USB due to a great mix of price and performance.

Micro USB PCB Orientations & Mounting Types

Micro USB connectors are produced in a varied and versatile range of PCB orientations and mounting types. Options available for top, middle, bottom and reverse horizontal mounting, as well as a range of unique vertically mounted products.

Vertical Mount Receptacle - GCT's wide range of vertical Micro USB2.0 connectors includes through hole and SMT types, with a variety of shell stake lengths, profiles and cable assembly lead in options. Example shown USB3140 SMT View all Vertical Micro USB Connectors

Vertical Mount Plug - Ideal for docking applications. Example shown USB3150 Through hole View all Vertical Micro USB Connectors

Bottom Mount - Soldered to the bottom side of the PCB. Example shown USB3080 Surface mount

Bottom Mid Mount - Fits in a hole cut in the PCB and is soldered to the underside of the PCB. As well as contacts, it also has solderable feet which provide extra strength. Example shown: USB3070 Surface mount

Bottom Mid Mount - Fits in a hole cut in the PCB and is soldered to the top side of the PCB. As well as contacts, it also has solderable feet which provide extra strength. Example shown: USB3155 Surface mount

Top Mount - Connector is soldered to the top side of the PCB. Also known as micro USB reverse type. Reverse types allow the physical body of the Micro USB connector to sit on top of the PCB but still accept µUSB cable plugs in standard orientation with the USB symbol facing upwards. B type connectors are polarised, and to allow the correct cable orientation. Example shown: USB3135 Surface mount (Through hole shell stakes)

Micro USB Mating Configurations

The table below shows compatible mating configurations between Micro USB interface types. There are also Micro USB 3.0 'SuperSpeed' connectors which have an additional 5 pins and difference interface shapes. These will also accept Micro USB 2.0 plugs depending on configuration, but will only run USB 2.0 specification.  GCT no longer produce Micro USB 3.0 connectors as the format has been superseded by USB-C.
