The USB plug is available in various sizes and with different connection schemes. The mini-USB plug is a smaller version of the USB plug. A further reduction is given with the Micro-USB plug.
Mini- USB connector comes in different variants designed for different applications. It comes in Type A, Type B and Type AB variants. They are 5-pole and are characterized by reduced dimensions compared to the USB plug. The size is about 60% less than the standard USB connector. For example, the type A has a width of only 6.9 mm in the mini version compared to 12 mm in the standard version.
Type A connectors are designed for use in computers, while type B connectors are used in peripheral devices. Type AB allows connection of both type A and type B cables, and in this way can be used both on the computer side and on the peripheral side. The connectors are usually designed in SMT technology and can be soldered directly onto the board. The mini-USB interface corresponds in its characteristics to the USB interface according to 2.0 with transfer rates of up to 480 Mbit/s.
Mini-USB interfaces are ideal for portable devices, such as notebooks, handhelds and PDAs. An even smaller version is the micro-USB connector for MP3 players or digital cameras.
The range for mini-USB includes a variety of mini-USB plugs and mini-USB sockets as mounting sockets in mobile devices and for through-hole mounting. They are available for a wide range of applications and protection classes up to splash- proof. For the interface adaptation from a mini-USB plug to a micro-USB plug, there are corresponding adapters, in straight and angled design.
