|  Tekin FXR Capacitor?
The capacitor on my tekin FXR just broke and ill need a replacement ASAP. I heard that you can just go down to radio shack and buy one as long as the specs are the same or better. But if that is what i do, do i have to replace the capacitor on the other ESC too being that i have two in my berg.  |

You want to get caps that are low ESR and rated for 105C. I don't believe they have these at RadioShack. A higher ESR cap rated for 85C is usually what they have, they may work but I always use low ESR and 105C. That's what all the ESC mfgrs use, I wouldnt go with anything spec'd lower. I buy mine on Ebay, search for low ESR cap. NOTE: I'm used to 1/8 brushless vehicles that are much harder on the ESC, since a crawler is much easier on the ESC the 85C higher ESR caps might be fine, but better to stick with what the ESC mfgr spec'd IMO Last edited by simplechamp; 07-14-2011 at 05:14 AM. |

I got it in and as soon as I plugged in the battery the copacitor puffed up and smoked. Every thing is fine but I'm still without a capacitor.

For the heck of it I'm searching ebay an I don't see any 16v 105c 360uf. But is 360uf the minimum (the uf is the amount it can store right?)? IE, could I get a 105c 16v 470uf ... like these: http://cgi.ebay.com/Fujicon-Electrol...item5ae11e5e43 Feel free to educate me. Last edited by Locked Up; 07-14-2011 at 07:04 PM. |

I was reading some stuff today that the UF is fine as long as it's higher or the same. I think I messed up by buying a 35v I thought it just ment I could use a higher voltage battery. Well better luck next time. I think to get the right on i will have to order it.

 that's what I was looking for. Now that I think about it do I really need a capacitor because I talked to a guy my LHS and he said that it dosnt really matter with a crawler because you are giving the esc huge bursts of power for a long periods of time? Is this correct, sounds right.

| Re: Tekin FXR Capacitor?
Sorry to bring back an old thread - caps pop because: 1. they've been subjected to overvoltage 2. cross polarised, i.e. negative polarity on the cap must be negative powered 3. short circuit A 35v 470uf should be ok if fitted correctly |
