Capacitor specs?

[antnee]

I need to get a new capacitor for my Xceleron ESC (1/10th scale), nipped into maplins today and theres loads!

What specs should I be going for?(Voltage, capacitence, etc) Also what 'type' should I get?

[westie]

I use 16v 4300uf

[MikePimlott]

Aluminium Electrolytic Radial 85 or 100 degrees

across the Lipo 16V anything from 2200uf to 4700uf (the more microfarads the bigger the case size, check dimensions.

Across the BEC 10V will be ok.

Most systems use the radial electrolytic caps.

The voltage rating needs to exceed the max votage that it is going to see and the capacitance needs to be large enough for any spiked/ demands.

Westie has recommended a 16V rated one with a capacitance of 4300uF

I have also seen 25V rated 2200uF capacitors recommended.

16V+ will be fine.

Ripple current capability will also be important. I have seen blown capacitors on PWM systems before due to an inadequate ripple current rating of the capacitor. This was none RC car related though I hasten to add.

This is what Hobbywing recommend as their 'super' capacitors

Basically 16V 1320uF with high ripple capability.

Hope this information helps some what......

To add to Mikes.
A 16V 4300 uF will be a different size to a 25V 4300uF, so check the dimensions so you don't end up with something as big as the car!! For example a 400V 4300uF would be about 15cm long!

Should either of these be ok?

222uF 16v

4700uF 16v

According to Novak there power trans cap (Here) for the gtb will work with any brushed/brushless speed controlled (expect high voltage esc's) and that is only a 5600uF 10V one.......
