KEMET Introduces True Fail Open Tantalum Capacitor
KEMET Corporation has introduced its new T496 Hi-Rel Fused Commercial-Off-the-Shelf (COTS) MnO2 Series of tantalum surface mount capacitors. These devices are ideal for use in high reliability applications where a capacitor failing short will disrupt the overall performance of the system. The internal fuse in the capacitor results in a fail open condition.
"KEMET's T496 COTS Series offers our customers a true fail open tantalum capacitor," stated Dr. Philip Lessner, KEMET's Senior Vice President, Chief Technology Officer and Chief Scientist. "Fuse actuation makes it possible for this failure mode to eliminate any concerns with parts failing short by ensuring that the capacitor is isolated from the circuit, thereby increasing overall reliability."
The T496 Hi-Rel Fused COTS MnO2 Series is available in DLA (DSCC) Drawing 04053 and can be ordered with a variety of options including surge current testing, Weibull Grading, termination options, and various ESR levels. A customizable testing and screening protocol is available upon customer request.
Typical applications include decoupling and filtering in computing, telecommunication, defense, and industrial end applications requiring a built-in fuse capability. This includes filtering for point of load and switch mode power supplies.
Typical markets include defense and aerospace, computer, industrial, lighting, and telecommunications. These devices range in price from $0.50 and higher, and complement KEMET's T493, T497, T513, T540, T541, and T543 series of COTS capacitors.

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.
