temperature. Larger capacitor values are usually com-

posed of X7R, X5R, Z5U, or Y5V dielectric materials.

Large ceramic capacitors (i.e., larger than 2.2μF) are

often available in low cost Y5V and Z5U dielectrics, but

capacitors larger than 1μF are not typically required for

AAT3195 applications.

Equivalent Series Resistance

ESR is an important characteristic to consider when

selecting a capacitor. ESR is a resistance internal to a

capacitor that is caused by the leads, internal connec-

tions, size or area, material composition, and ambient

temperature. Capacitor ESR is typically measured in mil-

liohms for ceramic capacitors and can range to more

than several ohms for tantalum or aluminum electrolytic

capacitors.

Capacitor area is another contributor to ESR. Capacitors

that are physically large will have a lower ESR when

compared to an equivalent material smaller capacitor.

These larger devices can improve circuit transient

response when compared to an equal value capacitor in

a smaller package size.

Ceramic Capacitor Materials

Ceramic capacitors less than 0.1μF are typically made

from NPO or C0G materials. NPO and C0G materials

generally have tight tolerance and are very stable over
