ESR

Capacitors with X7R or X5R ceramic dielectric should

be used for their low ESR and superior temperature

and voltage characteristics. Y5V capacitors should not

be used as their temperature coefﬁcients make them

impractical for this application. The following tables

lists the manufacturers of recommended capacitor and

inductor options.
