Jaro Offers Embedded "Skive" Coolers

By embedding a leading-edge 50x50x13 mm fan inside of a skived-copper-fin heatsink, Jaro Thermal Inc.'s unique "Skive" Cooler significantly reduces height requirements for low-profile applications, while providing unsurpassed surface-area. The dense arrangement of thin copper fins offers high thermal conductivity. Applications are expected to include network interface cards, video graphic cards, PCI express & IC spot cooling. These coolers are available with customizable fin thickness & pitch.

Energy Efficiency with Class D Amplifier Modules

Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure

Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
