Type 3191, Aluminum Electrolytic Screw Terminal
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 withstanding and excellent heat
transfer for higher ripple current.
