These Premium ELKO electrolytic capacitors are made in Germany using smooth foil.
The smooth foil gives them extremely low ESR, ESL, Low loss factor, and Low dielectric absorbtion.
This results in better sonic properties than the normal etched foil electrolytics.
They are rated at 70vdc, -400C to +850C, and have a tight +/- 5% Tolerance.
Due to the ongoing issues with sourcing materials, These are no longer being made. What I have in stock is the last of them. When these are gone, they can not be restocked.
