Everyone knows that the perfect capacitor to decouple the power rails around ICs is a 100 nF ceramic capacitor or equivalent, yet where does this ‘fact’ come from and is it even correct?

Exxelia has introduced four series of mica capacitors that meet the requirements of RF, military and aerospace applications.

For example, those 100 nF capacitors really ought to be placed within 10 mm of your chip if it’s operating at 100 MHz, but you can get away with even 10 cm if no signals go much above 1 MHz.

TDK's CGA and C series C0G MLCCs offer a capacitance of 10 nF at 1,250 V in a 3225 package for automotive and commercial applications.

Exxelia presents four series of mica capacitors, tailored to meet the stringent demands of radio frequency (RF), military and aerospace applications.
