KEMET WET TANTALUM CAPACITORS
Wet tantalum capacitors are usually applied in circuits where the AC component is small compared to the DC component.
Typical uses known to KEMET Electronics include blocking, by-passing, decopling, and filtering.
They are also used in timing circuits.
If two of these capacitors are connected “back-to-back” (i.
e.
, negative-to-negaive or positive-to-positive), the pair may be used in AC applications (as a non-polar device).
Operating temperature: –55˚C to +125˚.
APPLICATIONS: Filtering, bypass circuits.
Coupling and timing circuits.
Low source impedance circuits.
High charging current circuits.

failures that can occur in standard MnO2 Tantalum types.
Note also that KOCAPs may be operated at voltages up to 80% of rated voltage with equivalent or better reliability than standard tantalums operated at 50% of rated voltage.
The T520 series captures the best features of multilayer ceramic caps (low ESR and high frequency cap retention), aluminum electrolytics (benign failure mode), and proven solid tantalum technology (volumetric efficiency, surface mount capability, and no wearout mechanism).
The KO-CAP can reduce component counts, eliminate through-hole assembly by replacing cumbersome leaded aluminum capacitors, and offer a more cost effective solution to high-cost high-cap ceramic capacitors.
