USB Type-C: a look at data speeds, power delivery, and USB standards
Faster, Stronger, Higher said the Olympic motto: Faster, Smaller, Easier To Use could be an equivalent rallying cry for the electronics industry - and connectivity standards like USB in particular. By Bruce Rose, Principal Applications Engineer, CUI Devices
Using switched audio jacks to save space and add value
It appears that many of today’s mobile products are beginning to shun the trusty 2.5mm audio jack, in favor of wireless speakers or headphones. However, for a huge number of other products, this convenient, simple and universally recognised socket continues to offer robust and easy-to-use connectivity.

Low power encoders offer 12-bit and 14-bit resolutions
CUI Devices has announced the addition of two absolute encoder series, outputting 12 bits or 14 bits of single-turn absolute position information, to its line of AMT modular encoders. The AMT21 series, featuring high speed RS-485 communication, and the AMT23 series, designed with a Synchronous Serial Interface (SSI), are based on CUI Devices' proprietary capacitive sensing technology.
How to design with mini speakers for the best sound and reliability
Miniature speakers can be designed into a wide range of devices including door-entry systems, small timers or alarms, and various types of handheld and portable audio products. They can also be used to enhance the Human-Machine Interface (HMI) of equipment like industrial machinery, medical devices, computer peripherals, office automation and others.

The CBM‑75B, CBM‑97B, and CBM‑120B series utilise ball bearing construction, while the CBM‑50V and CBM‑60V series feature CUI Devices' omniCOOL system.
Are you a fan of DC fans?
Fans are all around us and form an integral part of our mechanised, electronics-centred lifestyles. From consumer appliances to large industrial machinery, devices we use every day rely on fans to expel hot air and keep them cool enough to operate reliably.
Aluminum heat sinks improve heat dissipation
CUI Devices has added a heat sink product line to its portfolio of Peltier devices & DC fans. The aluminum heat sinks, available in both extruded & stamped versions, are compatible with TO-218, -220, -252, & -263 transistor packages. Designed to improve the heat dissipation of low & high power board level applications, these stampings & extrusions are conveniently measured under four conditions for thermal resistance, making i...
Modules deliver high performance and longer life
A new line of high performance Peltier modules have been announced by CUI Devices which boasts performance and reliability, thanks to its innovative arcTEC structure. This construction utilises a combination of thermally conductive resin between the ceramic and copper on the cold side of the module, high temperature solder, and larger P/N elements made from premium silicon ingot.
Waterproof micro-USB connector provides protection
CUI Devices announced the addition of a waterproof micro USB 2.0 connector to its USB product family. The UJ2W MIBH 4 SMT is a micro B type jack connector with an Ingress Protection (IP) rating of IPX7, offering protection from liquid and moisture in challenging environments. Thanks to its copper alloy contact terminals with 30 microinch (µin) gold over nickel plating and stainless steel shielding, the UJ2W MIBH 4 SMT is designed for h...
Lin and CUI release efficient stepper motor and encoder combo
