Micro-USB connectors from JAE Europe exceed accepted performance benchmarks

Designers seeking space savings by using Micro-USB interconnects can gain extra features, additional footprint savings and greater durability with the JAE DX4 series Micro-USB receptacles and cable assemblies.

The JAE DX4 series type-B and type-AB receptacles meet all specifications of the USB Implementers Forum (USB-IF) for Micro-USB, and include enhancements to the internal design to prevent lifting of the contact. A stronger insert moulding also enhances contact retention force, and the stainless shell material used is more rugged than the basic copper alloy accepted by the USB-IF documentation. With these enhancements the DX4 series achieves extraction force of 8N and mating durability of 10,000 cycles.

The Micro-USB standard occupies 45% less volume than the established Mini-USB format, with a mounted profile more than 1.5mm lower at 2.35mm. JAE DX4 receptacles save an extra 0.4mm over the standard Micro-USB width by using an optional revised hold-down design. This provides two through-hole retainers as well as four surface-mount hold-down pads. This total of six solder points produces a more rigid PCB attachment in addition to the space savings.

The Micro-USB standard also increases the maximum current rating to 1.8A from 1.0A and supports USB On-The-Go, enabling ad hoc communication between portable devices. The DX4 series meets these specifications, allowing product designers to use the full capabilities of Micro-USB for powering and charging devices, and connecting portable terminals when no PC is present. Cable assemblies featuring DX4 plugs are supplied pre-assembled, and provide the option of Micro-USB to Micro-USB configuration, or Type-A USB to Micro-USB enabling equipment to be connected to a host PC.
The JAE Micro-USB DX4 series connectors and cables will deliver space savings and improved performance in products such as mobile phones, media players, digital cameras and PDAs, as well as other devices such as PC peripherals, docking stations navigation equipment, miniature security cameras and medical devices.

About JAE
Japan Aviation Electronics Industry (JAE) Limited was established in Tokyo in 1953 as a manufacturer of electronic components and assemblies for the aerospace market. Since then, it has grown into a billion dollar organisation which designs and manufactures standard and custom products ranging from connectors and switches to operating panels, displays, optical data links and space systems. JAE is among the world's top ten manufacturers of electronic connectors, a position that it has attained as a result of very high levels of investment in R&D. Over 70% of the company's revenue now comes from sales of connectors into applications in the telecommunications, computing, consumer electronics, automotive and aerospace sectors.

The company's standard connector portfolio incorporates high-precision, high-quality through-hole and surface-mount devices for board-to-board, board-to-cable and board-to-FPC/FFC applications, alongside PC card connectors, IC sockets and a variety of rectangular and circular devices. As well as the standard range of products, high levels of in-house design and production expertise allows JAE to rapidly engineer and manufacture custom interconnection solutions with as little as 12 weeks from drawing board to customer delivery.
