As far as I''m aware, ceramic capacitors have negligible leakage to the point where I''ve actually never seen a leakage current spec for them. You could try using a bunch of ceramics - they exist in values up to 220µF last time I checked, and the ability to make higher value ceramics has radically increased just over the past decade.

The actual leakage current that a capacitor experiences in a circuit depends on various factors, such as the capacitance of the capacitor, the voltage rating, and the temperature. High temperatures can increase the leakage current of the capacitor, so it is important to ensure that the temperature rating of the capacitor is appropriate for …
For electrolytic capacitors, DC leakage current (DCL) is a special characteristic that other conventional capacitors do not have. This current is represented by the resistor R leak in parallel with the capacitor in the series-equivalent circuit of electrolytic capacitors.
Leakage current can be modeled as a resistance in parallel with the capacitor. This model oversimplifies the voltage- and time-dependence of leakage current. Leakage current discharges a charged capacitor that has no external connections to its terminals. This process is called self-discharge. Note that a leakage current of 1 µA on a 1 F capacitor
Ideal capacitors will theoretically have a perfect insulating dielectric material and thus will have no leakage current (infinite insulation resistance) with DC voltage. However, real MLCCs will have imperfect dielectric materials, resulting in a measurable insulation resistance and leakage current. ... For example, a short and wide capacitor ...
Capacitor leakage current (IL ) is an important device parameter that can be alternatively expressed in terms of insulation resistance (Rp). These two parameters are related by the equation IL = Vw / Rp, where Vw is the working voltage specification of the capacitor.
Mica capacitors can withstand high voltages, operate at high temperatures and have low leakage current. Because mica capacitors have a very small inductive characteristic and low losses, they are often used in radio frequency (RF) circuits. Silver is used to form mica capacitor plates. Other metals, like copper and aluminum, …
Fig. 1: Leakage currents are dangerous for human beings when the ground conductor is disconnected. Such fault currents have a high resistive component as opposed to leakage currents, which predominately have a capacitive reactance. The RCD, however, cannot distinguish between the different types of ground currents.
Given a fixed voltage, the capacitor current is zero and thus the capacitor behaves like an open. If the voltage is changing rapidly, the current will be high and the capacitor behaves more like a short. Expressed as a formula: [i = C frac{d v}{d t} label{8.5} ] Where (i) is the current flowing through the capacitor, (C) is the …

Hence, replacing T491 capacitors with 470µF of T489 devices can achieve a valuable reduction in leakage current. In tantalum capacitors, the leakage current is heavily dependent on the ratio of rated applied voltage to rated voltage, due to the link between voltage rating and dielectric thickness.
An ideal capacitor is lossless, meaning the capacitor store charge and delivers the same amount of charge as output. But in the real world, capacitors have a small value of finite internal resistance. This resistance comes from the dielectric material, leakage in an insulator or in the separator.
Current Capacity: Similarly, capacitors have a maximum current capacity. Exceeding this capacity can lead to overheating and failure. Ripple Current Exceeding Specifications. Ripple Current: In power supplies, capacitors are subjected to a ripple current, which is the AC component of the current in a predominantly DC circuit.

built-in current limiting. For a given capacitor, a larger applied voltage within the voltage rating of the capacitor, will give a larger leakage current. Measuring a larger current with the same intrinsic noise floor produces a greater signal-to-noise ratio, and a more accurate reading. For capacitors with high voltage ratings, a 1000V source ...

In most electronic devices, the DC current signal applied to a circuit has an AC portion. This AC portion is referred to as the ripple current. Some capacitors have high ripple current ratings while others have low ripple current ratings. Although there are standards for calculating these ratings, some manufacturers use their own techniques.
intrinsic leakage currents have a strong dependence on the electric field, and subsequently, on the thickness of the dielectric. In contrary, the absorption currents depend mostly on the value of capacitance. Fig. 2. Distribution of leakage currents in 1 F, 50V capacitors measured after 60 seconds and 1000 seconds of electrification.
DC leakage current is a sign of effective ageing. After ageing, the capacitor is tested, sleeved and labeled, packed and finally shipped.

While it may at first appear that an electrolytic capacitor is two conductive alumi-
For instance, operation of DC rated capacitors at high AC current levels can cause a localized heating at the end terminations. The localized heating is caused by high 12R losses. ... If the internal pressure becomes great enough, it can cause a breach in the capacitor, which can then cause leakage of impregnation fluid or moisture susceptibility.
