Multilayer Ceramic Capacitors (MLCCs)
KEMET Multilayer Ceramic Capacitors (MLCCs) offer tremendous performance, reliability and cost
advantages for circuit designers. Our comprehensive line of surface mount and through-hole devices
are utilized in a variety of computer, telecommunications, automotive, military, medical and consumer
electronics. Primary applications include decoupling, filtering, bypassing and smoothing.
Ceramics are non-polar devices which offer unsurpassed volumetric efficiency, delivering the highest
capacitance in the smallest package sizes in the market. Available in a wide range of sizes, KEMET
MLCCs offer very low equivalent series resistance (ESR), exhibit excellent high frequency characteristics
and are extremely reliable. KEMET is driving ceramic technology advancement, resulting in smaller case
sizes, better performance and lower cost. These factors have accelerated the progression of readily
available ceramics into markets and applications previously occupied by tantalum, aluminum and film
capacitors, lowering the risk of material shortages.
MLCCs are monolithic devices that consist of laminated layers of specially
formulated, ceramic dielectric materials interspersed with a metal electrode
system. The layered formation is then fired at high temperature to produce a
sintered and volumetrically efficient capacitance device. A conductive
termination barrier system is integrated on the exposed ends of the chip
to complete the connection. KEMET offers one of the broadest product
portfolios of ceramic capacitors in the industry, providing customers the right
combination of dielectric, termination system, form factor and screening.
Ceramic MLCCs are offered in temperature and voltage stable C0G (NP0), temperature stable
X8R, XR and X5R as well as general purpose X8L, Z5U and Y5V dielectrics. KEMET provides
dielectrics in both base metal electrodes (BME) and precious metal electrodes (PME) technologies.
Military designated dielectrics such as BP, BX and BR, and a wide range of high temperature (to
260°C) and high voltage dielectric solutions for extreme environments are available.
KEMET offers a variety of termination systems including RoHS-compliant tin, tin-lead, gold
and custom options. KEMET’s Flex Mitigation products reduce risk of flex-related board failure
and provide a benign failure mode.
Surface mount, through-hole, J-leads, L-leads, S-leads, stacked and modules are some of the
form factors that KEMET produces. Customers can tailor a part for their requirements.
KEMET offers parts that meet varying testing and screening levels. This includes general
purpose commercial grades, automotive grade (AEC-Q200), medical grades and parts qualified
to many military specifications.
KEMET’s standard ceramic products meet RoHS criteria and are compatible with modern solder
processes including multiple reflow passes.
