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.

Highlights

- Stud mount available

- High current application

- Industrial applications

- Smoothing and filtering

- Audio power supplies
