Lastly, any non-X/Y rated capacitor needs to be checked if it is capable of handling the expected current ripple. Some technologies to get higher capacity at high voltage cause high ESR in this type of capacitor, which makes them unsuitable for e.g. SMPS usage. I think this is all there is to it, let me know if I forgot something or borked up.

Larger capacitors respond well to DC signals, but tiny chip capacitors offer a far higher frequency response. Conclusion. If a capacitor is larger, its charge/discharge rate will be slower. Smaller capacitors have higher resonance points due to their lower ESL and are thus better for high frequency bypassing. The design of the …

Discrete capacitors deviate from the ideal capacitor. An ideal capacitor only stores and releases electrical energy, with no dissipation. Capacitor components have losses and parasitic inductive parts. These imperfections in material and construction can have positive implications such as linear frequency and temperature behavior in class 1 ceramic capacitors. Conversel…

Using a lower-rated capacitor means it''ll draw less energy. This will decrease the efficiency of the device. In the long run, the AC components can get damaged. The correct replacement for a 40/5 uF capacitor is the 40/5 uF capacitor itself. But you can still pick a 45/5 uF capacitor if you want to.
Dual capacitors are usually rated for 370V or 440V. Use a capacitor that has the same or higher voltage as your system voltage. Never select one that has a lower voltage rating than your system voltage. Frequency. Most capacitors will be rated for both 50 and 60 Hz. Oval vs. Round Case Style.

I''ve been looking at why only X rated capacitors are used. After spending some time searching the internet, I found that X rated capacitors are connected in series (line to line) with the circuit, while Y rated capacitors are connected in parallel (line to ground). The X rated capacitor is designed for 250, 400, 600 VAC.
Only Y class capacitors are sufficient for use in ''line-to-ground'' applications. Because of the stricter safety ratings, it is acceptable to use Y-rated capacitors in place of X-rated capacitors, but not vise versa. Capacitors explicitly rated for both are not uncommon, and there is nothing preventing a capacitor from being both …

Most capacitors are rated for a maximum temperature, and if they exceed this temperature, they will fail. There are two main ways that heat can damage a capacitor. The first is by causing the electrolyte inside the capacitor to dry. This reduces the capacitance of the capacitor and can eventually cause it to fail entirely.
