Ceramic Capacitors
Ceramic capacitors use ceramics as a dielectric, stacked
with metal layers. These devices are ideal for applications
with high voltage, high frequency, high power
demands, and high temperatures, like the petroleum,
automotive, avionics and other industries, and as multilayer
ceramic capacitors (MLCCs). Ceramic capacitors
have a high dielectric constant (high-K) and allow
relatively high capacitance in a small physical size.
Some types of ceramic capacitors can be used in
temperatures far above 200°C, beyond the limitations
of other capacitor types.
Lacquers are often used to keep moisture and ambient
influences from affecting ceramic capacitors. We offer a
full suite of materials for protecting ceramic capacitors
against humidity, dust and mechanical stress.
