Um conversor de tensão DC-DC geralmente realiza a conversão aplicando, com determinada frequência (usualmente na faixa de 100 kHz a 5 MHz), uma tensão contínua pulsada em um indutor (ou capacitor), fazendo com que o fluxo de corrente gere energia magnética (ou elétrica) armazenada, que é então aproveitada em uma saída ...

Whenever the capacitors are in series and AC is applied, the capacitive reactance for each capacitor behaves as resistors do. The X C is added together for capacitors in series. See the following equation:
2. DC-DC Converter Output Filtering: Capacitors are used to filter out the high frequency switching noise generated in DC-DC converters. 3. Coupling: Capacitors are used to couple two circuits together, allowing AC signals …
When a dc source is connected to a capacitor, the capacitor gets charged and after charging no current flows in the circuit and the lamp will not glow. There will be no change even if C is reduced. With ac source, the capacitor offers capacitative reactance `(1//omegaC)` and the current flows in the circuit.
Since the datasheet for that capacitor specifically says "Installation: Any position", it is a non-polarized capacitor that is suitable for both alternating ("AC") and constant-polarity ("DC") applications. (As I could have guessed just from the description "film capacitor"). Capacitors that are directly connected to mains voltage should meet safety …

In a DC circuit, a capacitor acts as an open circuit and does not permit current to pass. In an AC circuit a capacitor has an effect because it acts as a current reservoir while the current is changing.

AC capacitor circuits. Capacitors do not behave the same as resistors. Whereas resistors allow a flow of electrons through them directly proportional to the voltage drop, capacitors oppose changes in voltage by drawing or supplying current as they charge or discharge to the new voltage level.

As mentioned previously, a capacitor passes AC signals and blocks DC signals. So if you put a capacitor in series with something, it blocks the DC signal, removing unwanted DC offsets. If you put a capacitor in parallel with something, it shunts AC signals, often this is connected to ground so that you can shunt any unwanted AC signals to ...
