filter
A high-frequency signal will see the capacitor connected to ground, and travel through it, since it is a low impedance path, but a low frequency signal will not be affected by it. The capacitors to ground form a low
Using capacitor with lower voltage than the specified one
For example, I would choose a 63V capacitor for a circuit running at 45V. Your circuit is running at plus minus 20V. A capacitor voltage rating of 25V is marginal, so I would choose a capacitor
How do I increase the voltage limit by connecting
This can be mitigated by adding resistors across each capacitor that have values lower than the effective leakage resistance of the capacitors. If the cap has a leakage R of (say) 10M$Omega$, go for 1M$Omega$
High-voltage capacitor in a low-voltage system
A leaky capacitor has the effect of a large rated capacitor that leaks and keeps the circuit from working properly. In most cases, you can over rate a capacitor and get away with it. If you double the voltage value of the capacitor but keep

6 FAQs about [How to add a capacitor at the low voltage end]
What is a capacitor at low voltage?
Capacitors at low voltage are dry-type units (i.e. are not impregnated by liquid dielectric) comprising metallised polypropylene self-healing film in the form of a two-film roll. Self-healing is a process by which the capacitor restores itself in the event of a fault in the dielectric which can happen during high overloads, voltage transients, etc.
Should I use a high voltage or low voltage capacitor?
Of course, for conventional electrolytic capacitors, it is simply more cost effective to use a capacitor with a higher voltage rating, or a bunch of high voltage lower value capacitors in parallel. At a simpler level, for low duty cycle / low load applications, a passive balancing approach can be adopted.
How do I reduce the leakage of a capacitor?
This can be mitigated by adding resistors across each capacitor that have values lower than the effective leakage resistance of the capacitors. If the cap has a leakage R of (say) 10M Ω Ω, go for 1M Ω Ω resistors. Any variation will be reduced by about 10:1 BUT, I'd suggest you wouldn't get better than 1.9 x original voltage rating.
How do I choose a capacitor?
In practice, one always chooses a capacitor with voltage rating somewhat in excess of the highest voltage the capacitor might be exposed to. For example, I would choose a 63V capacitor for a circuit running at 45V. Your circuit is running at plus minus 20V.
How do you connect a series capacitor?
Connect Positive to Negative: Link the positive (+) terminal of one capacitor to the negative (-) terminal of the other. This forms a series connection between the capacitors. Measure Total Voltage: The total voltage across the series-connected capacitors equals the sum of their individual voltages.
What happens if a capacitor meets a higher voltage threshold?
However, it is far better to get a single capacitor that meets the higher voltage threshold on its own as combining capacitors in series will also lead to a higher Effective Series Resistance (ESR). In the scenario above, you will double the ESR. High ESR can cause unwanted or catastrophic effects on circuits not designed to handle it.
