In order to meet the growing demand for higher capacitance in surface mount high voltage MLCCs, KEMET has increased its capacitance offering by up to five times across most of its X7R dielectric platform. Available capacitance has been increased in EIA 1206 thru 2225 case sizes with rated voltages up to 3000VDC.

"Advances in KEMET's base-metal-electrode (BME) X7R high voltage technology have led to the development of some of the highest capacitance values available in the industry, including first-to-market," said Reggie Phillips, KEMET Specialty Product Manager. "These new CV values will promote optimization and downsizing opportunities of existing designs and promote usage in applications requiring capacitance values previously unattainable in a high voltage ceramic capacitor," continued Phillips.

KEMET High Voltage MLCC devices exhibit low leakage current and low ESR at high frequencies. As an option, they are available with KEMET's flexible termination technology which inhibits the transfer of board stress to the rigid ceramic body, therefore mitigating flex cracks which can result in low IR or short circuit failures. Tin-lead termination finish is also available for higher reliability applications.

Typical applications for X7R High Voltage MLCCs include power supply, LCD fluorescent backlight ballasts, HID lighting, telecom equipment, industrial and medical equipment/control, LAN/WAN interface, analog and digital modems, and automotive lighting. Typical markets are alternative energy, industrial/lighting, medical, telecommunications, transportation, and defense and aerospace.

Technical Information
KEMET's high voltage surface mount MLCCs are manufactured in state of the art ISO/TS 16949:2002 certified facilities and are available in both commercial and automotive grades. Automotive grade devices meet the demanding Automotive Electronics Council's AEC-Q200 qualification requirements.
