High Voltage Bulk Capacitors feature vertically stacked design.
November 26, 2012 -
Utilizing lead-frame technology to vertically stack 1 or 2 multilayer ceramic chip capacitors into single surface mount package, KPS Series in X7R dielectric is available in rated voltages of 500 and 630 Vdc. Lead-frame isolates capacitors from PCB, providing advanced mechanical and thermal stress performance and addressing concerns for audible microphonic noise that may occur when bias voltage is applied. Offering board flex capability up to 10 mm, devices operate from -55 to +125°C.

KEMET Introduces New Ceramic High Voltage Bulk Capacitance Solution at Electronica 2012
The KPS High Voltage Series in X7R Dielectric Offers Highest Capacitance/Voltage Combinations in the Industry
GREENVILLE, S.C., -- KEMET Corporation (NYSE: KEM), a leading manufacturer of tantalum, ceramic, aluminum, film, paper and electrolytic capacitors, today introduced its new KEMET Power Solutions (KPS) High Voltage stacked capacitors in X7R dielectric at Electronica 2012 in Munich, Germany.

KEMET's KPS Series High Voltage devices utilize a proprietary lead-frame technology to vertically stack one or two multilayer ceramic chip capacitors (MLCCs) into a single compact surface mount package. The two-chip vertically stacked device offers up to double the capacitance in the same or smaller design footprint, allowing for both component and board space reductions.
"KEMET now offers some of the highest CV values available in a 2220 footprint," stated Craig Scruggs, KEMET Specialty Ceramics Product Manager. "These high voltage bulk capacitance devices are available in rated voltages of 500 VDC and 630 VDC, have lower ESR and ESL properties than competitive technologies, and present optimization and downsizing opportunities of existing high voltage designs. We are very pleased with the response it is receiving at Electronica," continued Scruggs.
With an operating temperature range of -55 degrees Celsius to +125 degrees Celsius, KPS Series devices provide superior flex performance over traditional surface mount MLCCs with board flex capability up to 10 mm. The lead-frame isolates the capacitors from the printed circuit board, thereby providing advanced mechanical and thermal stress performance and addressing concerns for audible microphonic noise that may occur when a bias voltage is applied. They are also environmentally friendly, capable of Pb-free reflow profiles and are available in both Commercial and Automotive Grades. KPS Series Automotive Grade capacitors meet the demanding Automotive Electronics Council's AEC-Q200 qualification requirements.
KPS devices are ideally suited to a wide range of applications which include switching power supply smoothing circuits, snubbers in lighting ballasts circuits, and high-voltage coupling/DC blocking in inverters.
