The low ESR of Type 3191 capacitors makes them

a great choice for output filtering in switching and

audio power supplies. It’s available with the capacitor

element potted in place for lowest cost or secured by

rill, spoon shaped dimples in the side of the can. Rilled

construction offers high vibration and shock with-

standing and excellent heat transfer for higher ripple

current.
