What capacitors are these? -
06.26.2009, 02:38 PM
Hoping someone can give me a little insight.. THis little capacitor board came with my sidewinder esc in a Rc10b4... for the life of me I can not find any information on the board or even the capacitors on it, im trying to figure out if I should replace them with the caps i have lying around (25v 330uF 105c low esr).
The capacitor reads F 7x3b 331 16 The (what I think are) resistors read Pj7D sx34 Pics:   Thanks, Ben edit- holy crap my phone has an amazing camera

They look like some solid polymer capacitors... very durable, esc's should have been using them for years now. Lower esr, and smaller than standard liquid electrolytic caps.

Those aren't resistors, they're diodes.
As for the capacitors, they're solid electrolytic capacitors, which use polymer as electrolyte. |

Can someone explain what those diodes and resistors do in this application?
I have allways thought that capasitors are enought. |

looks like the caps on my burned etti-boat esc and like the cap-board lutach showed in his esc-thread.
when it is delivered with your esc I suppose that it makes sense to use it!? otherwise they would'nt have used these. they won't do that just for fun. flo |
