Type 3191
Aluminum Electrolytic, Screw Terminals, Switching and Audio Output
Screw Terminal Capacitors for Power Output Filtering
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.
