Hi guys. I am designing an EMI filter for a light dimmer circuit, to filter the incoming 230Vac (50Hz) source. The damping capacitor, according to calculations should be 23.5 uF, so lets say 25uF for ease of use. Polypropylene film capacitors rated to 230Vac are HUGE!!! ~55mm or greater in height! How does one get around this? It's connected between the live and neutral terminal of the source, so unfortunately an electrolytic won't be able to be used. Any ideas? I've searched the Polypropylene film and Polyester Film capacitors, and they are ALL to large to be practically be implemented in the circuit, at that capacitance, at that voltage. Is there perhaps some mystical type of capacitors that I have missed, that could provide the right capacitance with high ESR in a small package, that can handle 230Vac? Any advice would be greatly appreciated.
