KEMET Introduces First-to-Market High Temperature Multilayer Stacked Capacitors with an X8L Dielectric for Commercial & Automotive Applications

KPS HT Series devices offer high temperature reliability and up to double the capacitance in the same or smaller footprint

GREENVILLE, S.C., May 15, 2013 — (PRNewswire) —   KEMET Corporation (NYSE: KEM), a leading manufacturer of tantalum, ceramic, aluminum, film, paper and electrolytic capacitors, today introduced its new KEMET Power Solutions High Temperature (KPS HT) multilayer stacked capacitors.

KEMET's KPS HT Series devices with an X8L dielectric 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.

"These devices exhibit a predictable change in capacitance in respect to time and voltage, and feature a minimal change in capacitance in application temperatures up to 150 degrees C," said Craig Scruggs, KEMET Specialty Ceramics Product Manager. "In addition, the construction of 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," continued Scruggs.

Providing up to 10mm of board flex capability, KPS HT Series capacitors are environmentally friendly and in compliance with RoHS regulations. They are also capable of Pb-Free reflow profiles and provide extremely low ESR and ESL. Utilizing an X8L dielectric, these devices can provide reliable operation up to 150 degrees C and are well suited for high temperature filtering, bypass and decoupling applications.

Typical markets include alternative energy, industrial/lighting, medical, telecommunications, automotive, and defense and aerospace. KPS HT Series stacked capacitors complement KEMET's extensive high temperature product portfolio, with capacitance solutions available for extreme temperature applications up to 260 degrees C.

Technical Information

In addition to Commercial grade, Automotive grade devices are available and meet the demanding Automotive Electronics Council's AEC-Q200 qualification requirements.
