Kemet Capacitors 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.

Kemet Capacitors 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.

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. T520 SERIES—KO-CAP POLYMER TANTALUM The KO-CAP is a tantalum capacitor, with Ta anode and Ta205 dielectric. However, a conductive, organic, polymer replaces the MnO2 as the cathode plate of the capacitor. This results in very low ESR and improved cap retention at high frequency. T525 SERIES—KO-CAP POLYMER TANTALUM The T525 has been targeted for power management applications. This series offers all of the same advantages as the T520 KO-CAP including very low ESR, improved capacitance retention at high frequency and a benign failure mode, to go along with 125˚C capability.
