I noticed this high voltage module has an electrolytic capacitor on the input, which makes sense because the device uses a high frequency oscillator to generate the high voltage, and the capacitor keeps the high frequency signal from the oscillator from leaking back onto the power wires (which could then radiate and cause RF interference). But what does the green color of the capacitor mean? Does that mean it has a low inductance? I've heard of certain capacitors for high frequency applications that have low inductance, but these are also usually lower capacitance capacitors (like 1uF or less), and they usually aren't electrolytic. But this is an electrolytic capacitor with 100uF capacitance, and it has an unusual color scheme. So I was wondering if the green color here (as well as the gold colored writing on the capacitor) is a color code for being a low inductance high capacitance electrolytic capacitor? If so it would indeed be pretty rare, as I can't find anything on Google regarding low inductance electrolytic capacitors (something I looked up, because I suspected that this might be such a capacitor).
Here's a picture of the high voltage module.

I bought the high voltage module (not the one from eBay, but one that's even cheaper from AliExpress), and it doesn't have the power input capacitor. Instead, there's a blank place on the circuit board to solder your own. So I'm going to need to buy one of these capacitors, and I want to make sure I'm buying the correct type.
