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 voltage filtering in switching and audio power supplies.

Standard encasement is with the capacitor element compressed onto

an aluminum peg in the can bottom and a phenolic peg in the top.

Optional Rilled construction is available. With rilled construction the

element is secured by rills, spoon shaped dimples in the side of the

can. Rilled construction offers the industry’s highest vibration and

shock withstanding capability and excellent heat transfer.

Highlights

- Stud mount available

- High current application

- Industrial applications

- Smoothing and filtering

- Audio power supplies
