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

for certain applications are based on the knowledge that the Cornell Dubilier company providing such
statements (“Cornell Dubilier”) has of operating conditions that such Cornell Dubilier company regards
as typical for such applications, but are not intended to constitute any guarantee, warranty or representa-
tion regarding any such matter – and Cornell Dubilier specifically and expressly disclaims any guarantee,

still occur. Accordingly, customer applications which require a high degree of reliability or safety should
employ suitable designs or other safeguards (such as installation of protective circuitry or redundancies
or other appropriate protective measures) in order to ensure that the failure of an electrical component
does not result in a risk of personal injury or property damage. Although all product-related warnings,
cautions and notes must be observed, the customer should not assume that all safety measures are indi-
cated in such warnings, cautions and notes, or that other safety measures may not be required.
