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.

Dielectrics

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.

Terminations

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.

Form Factors

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.

Screening

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.

Environmental Compliance

KEMET’s standard ceramic products meet RoHS criteria and are compatible with modern solder

processes including multiple reflow passes.
