What capacitors should be added to the ESC
More if it''s a higher current ESC. Voltage ratings of the capacitors should be (imo) at least double your battery voltage. DO NOT add capacitance to ESC-motor wires if extending these - this will cause bad things to happen. Reply reply ... I''ve added 1000µF capacitors, but I know that without the added caps the stock 330µF caps also work fine

ESC Capacitor Help
It should be lined up with one of the leads. That would be the negative, Ground, black lead. If it''s an axial lead capacitor, and it looks like it is, the arrow points at the negative lead. Get the polarity wrong and the capacitor will ''Blow'' and be ruined. Capacitors, like resisters, come in certain standard sizes.

Capacitors needed for brushed motor?
I read something about capacitors used to reduce radio interference from the motor in one of the threads here, and just noticed that the motor of my EasyGlider Electric ARF doesn''t have them. So I was wondering if I should add some, or if that may be handled by the ESC anyway (though I don''t really see how the ESC could do that).

How to extend ESC wires correctly
In the example above, the capacitor bank is soldered at the positive and negative terminal posts to the ESC wires. The battery wires to the ESC have been extended by 4 inches. In order to compensate a 460uf capacitor must be used. It doesn''t matter if you require one capacitor or three capacitors to get to 460uf or more.
What does the Voltage Rating on a Capacitor Mean?
A capacitor with a 12V rating or higher would be used in this case. In another, 50 volts may be needed. A capacitor with a 50V rating or higher would be used. This is why capacitors come in different voltage ratings, so that they can supply circuits with different voltages, fitting the power (voltage) needs of the circuit.
ESC Capacitors
He also did repeatedly say that any of the commercially available capacitors would not magically improve performance of the ESC. The only thing that could would be your battery. The capacitors are only there to smooth out the pulses caused by a brushless system. If you really want real performance gains, look into supercapacitors.
CAPACITOR: Best Capacitance Rating for 6S (KISS ESC/FC)
I am currently working on my second build, which will be a Caddx+KISS 5" 6S quad, and I purchased several types of 50V capacitors with varying capacitance ratings; 330uf, 470uf and 1000uf. The ESC is a KISS 2-5S 25A (40A limit) 32bit 4-in-1 and requires a capacitor when using anything above 5 cells. I understand that a 50V capacitor is the …
So I lost one of the capacitors on my ESC. It still flies okay... ish ...
Second, since you have a new esc coming in, don''t waste your time trying to resolder the cap. The caps are just used to filter the noise and stabilize the voltage going across the phases of the motor. It won''t damage anything but that motor may end up being choppy but once you replace the esc, it will be fine.
Filtering out ESC noise in Power for FPV
Little Bee ESCs (probably any damped light ESC) can be extremely noisy ranging from 5v-29v noise when being tortured. This is probably why they are known to kill video equipment. ... The wiring on the salvaged capacitor added resistance and inductance that is by definition going to diminish the benefit of the capacitor.
Understanding ESR and ESL in Capacitors
Here, the Capacitor C is an ideal capacitor, ... In a low noise power supply, where the noises need to be suppressed and the output filter stages should be low in numbers, high quality super low ESR and low ESL capacitors are useful for smooth output and stable power delivery to the Load. In such an application, polymer electrolytes …

Question about ESC capacitor
I guess I should have given a bit more on what I was up to. I am building a ZMR250 and I am going to run the Emax BLHeli 12a esc''s and the capacitor is getting in the way of mounting them like I want to. As I stated I can move them, the capacitors, to the PDB which will only amount to an increased distance of maybe 2 inches at the most.

Adding capacitor banks to ESC
Most people add capacitor banks to the ESC or reciever to help smooth the voltage sag that FE circuits see when under a heavy amp draw. The capacitor acts as a reservior to store current under lighter loads and then release current under heavier loads to even out voltage sag. Brownouts from sudden acceleration can actually cause some …
