KEMET Adds First-to-Market Capacitance Values to Its High Voltage Ceramic Capacitor Portfolio

GREENVILLE, S.C., Dec. 7, 2011 /PRNewswire/ -- KEMET Corporation (NYSE: KEM), a leading manufacturer of tantalum, ceramic, aluminum, film, paper and electrolytic capacitors, today announced the addition of several industry leading, as well as first-to-market, capacitance/voltage (CV) values to its High Voltage Multilayer Ceramic Capacitor (MLCC) portfolio in X7R dielectric.

Recent design and manufacturing technology innovations have led to significant increases in capacitance in EIA 0805 through 1812 case sizes and rated voltages of 500VDC, 630VDC and 1000VDC. KEMET maximum capacitance offerings are now up to seven times greater than those previously available.

"KEMET's latest product offers optimization and downsizing opportunities of existing designs," said Bill Sloka, KEMET Specialty Product Manager. "Development of these new CV values will create additional markets for High Voltage MLCCs and promote usage in applications requiring capacitance values previously unattainable in a ceramic capacitor."

For added reliability, KEMET's Flexible Termination technology is an available option that provides superior flex performance over standard termination systems. This technology was developed to address flex cracks, which are the primary failure mode of MLCCs and typically the result of excessive tensile and shear stresses produced during board flexure and thermal cycling. Flexible Termination technology inhibits the transfer of board stress to the rigid body of the MLCC, therefore mitigating flex cracks which can result in low IR or short circuit failures.

Automotive grade devices, which undergo stricter testing protocol and inspection criteria, are also available.  Whether under-hood or in-cabin, these capacitors are designed for mission and safety-critical automotive circuits for applications requiring proven, reliable performance in harsh environments.

Typical markets include power supply, LCD fluorescent backlight ballasts, HID lighting, telecom equipment, industrial and medical equipment/control, LAN/WAN interface, analog and digital modems, automotive (hybrid), military, and aerospace. Typical applications include switch mode power supplies (input filters, resonators, tank circuits, snubber circuits, output filters), high voltage coupling and DC blocking, lighting ballasts, voltage multiplier circuits, DC/DC converters and coupling capacitors in Cuk converters.
