KEMET Adds Polymer HermeticSeal Series to Its Tantalum Through-Hole Portfolio
KEMET has introduced its first-to-market T550 Polymer Hermetic Seal (PHS) Series of tantalum through-hole capacitors. PHS capacitors take high voltage management applications to new levels, providing up to 90% lower ESR, 40% increased ripple current capabilities, and improved capacitance retention at high frequency and low temperature compared to wet tantalum devices.
"KEMET is committed to providing our industry with first-to-market technology. It is what our customers have come to expect from us," stated Per Loof, KEMET’s Chief Executive Officer. "The T550 PHS Series has the lowest ESR in the industry and the highest ripple current capability in its class. In other words, we are providing capabilities that, before now, did not exist," added Loof.
"PHS offers the highest total capacitance at low temperatures and high frequencies, surpassing wet tantalum performance and rendering it the most economical high power solution available," said Dr. Philip Lessner, KEMET Vice President, Chief Technology Officer and Chief Scientist. "Additionally, solid internal construction drastically improves shock and vibration capability, all within an approximately 25% lighter package than the equivalent wet tantalum capacitor."
With its benign failure mode, T550 PHS Series products are ideal for use in high voltage power management applications such as buck boost converters, filtering, hold-up capacitors, and other high ripple current application. Typical markets include alternative energy, industrial/lighting, medical, defence and aerospace, and telecommunications.

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.
