6 FAQs about [Capacitor pole to shell]

Is a capacitor a ground terminal?

The capacitor is for EMI filtering, it is there to reduce common mode noise. Yes they are ground terminals. One is the ground reference for unisolated mains input side, the other one is the ground reference for isolated low voltage output side. Therefore it must be of special type for safety reasons, the type is called an Y capacitor.

How does parallel output capacitor network work?

In the parallel output capacitor network, ESR zero of each capacitor is still taking effect independently. Also, by putting two output capacitors in parallel, a parallel pole is introduced into the loop. The effect brought by the ESR zero and parallel pole depends on how close they are on the frequency axis.

Why do foil capacitors have a polarity mark?

Old paper and foil capacitors had a mark at one end to indicate which lead attached to the outer wrap of foil. That was so you could tie that lead to ground and help suppress radiation of noise. I know the polarity has to be correct, but many sources do not explain which way round is the correct polarity.

How do I connect an electrolytic capacitor?

To connect an electrolytic capacitor, you should connect the minus (-) side. Most electrolytic capacitors have a colored band on the minus side. Be sure to connect it correctly, as incorrect polarity can damage the capacitor.

Does an electrolitic capacitor have a + and a - connection?

An electrolytic capacitor does have a positive (+) and a negative (-) connection. Unlike diodes, they are not called cathode and anode. When using an operational amplifier (opamp) with a negative power supply, the negative (-) terminal of the electrolytic capacitor goes to the lower potential (VEE or -V).

Does a capacitor cause a zero?

I intuitively expect the capacitor to cause a zero for those high frequencies, not a pole. It does create a zero but only when the frequency is infinite. For more normal frequencies (such as the 3 dB point of an RC low-pass filter), there is a pole present but, it's not obvious when looking at a bode-plot.
