I want to buy some components to keep stock or for a future quad that I will build. these capacitor can be good ? https://it.aliexpress.com/item/100500207...6cM8U&mp=1 with what feature do I buy it? 10v 1000uf the choice depends if I use it with 4s or 6s? • Posts: 4,073 Threads: 75 Likes Received: 2,549 in 1,858 posts Likes Given: 3,949 Joined: May 2021 Reputation: 121 11-Nov-2021, 12:35 PM (This post was last modified: 11-Nov-2021, 12:36 PM by Lemonyleprosy.) Nope. Buy from a reputable electronic component dealer: Mouser.com Digikey.com Jameco.com This will give you a good rundown on what to use: https://oscarliang.com/capacitors-mini-quad/ Other than size and weight restrictions, it’s not gonna hurt to go with higher voltage (v) or higher capacitance (F, but we’re talking microfarads, so- uf [or mfd]). Low ESR is the bigger thing to pay attention to. But also, buying from a reputable source whose specifications you can trust. Dangerous operations. Disclaimer: I don’t know wtf I’m talking about. I wish I could get the smell of burnt electronics out of my nose. • Posts: 115 Threads: 5 Likes Received: 40 in 28 posts Likes Given: 10 Joined: Dec 2019 Reputation: 3 As I understand it you need low ESR capacitors and I'm not sure those are low ESR becaues I can't find that info on the page. Regarding feature the voltage needs to be over the battery voltage so for 4S thats 16.8 so I would go with 25V and 6S is max 25,2 so I would go 35 for them. The size depends a bit on what you can fit in your build but 470-1000 is pretty normal. • Posts: 21,408 Threads: 595 Likes Received: 9,037 in 6,688 posts Likes Given: 1,428 Joined: Jun 2018 Reputation: 796 Just get some Panasonic FR or FM series capacitors.

"JWCO" capacitors. I've never heard of that brand before so personally I would avoid using them. The Panasonic capacitor you linked to is 1500uF. You don't need anything that big. 1000uF is as big as you need to go on a 5" quad running 4S or 6S, and in some cases you can get away with a 470uF capacitor. If you have enough space in your quad, use a 1000uF capacitor. • Posts: 664 Threads: 121 Likes Received: 24 in 23 posts Likes Given: 490 Joined: Apr 2021 Reputation: 0 (11-Nov-2021, 02:34 PM)SnowLeopardFPV Wrote: "JWCO" capacitors.

A quick Google found these: https://www.drone24hours.com/product/con...esc-220uf/ https://www.drone24hours.com/product/35v...itor-rohs/ Yes unfortunately I'm used to buy stuff from Amazon but for drones small components more from AliExpress. https://www.mouser.it/ProductDetail/Pana...ig3w%3D%3D That should be fine ? The problem is that for a cheap components like that I risk to pay more shipping costs then the price of the components. Then I don't understand as on this video, is better to put the capacitor on the battery 1000uf or put on also on the ESC (300uf) ? But maybe he is referring to put one on each arm ESC ? But I never seen capacitor on any single arm ESC. In my case I have 4in1 so is where o plug in the battery is the ESC and I shouldn't have noise issues ? System let me decide these other shipping methods, but who know how much time will require and if there is a tracking: https://i.imgur.com/3t0NPs6.jpeg Does someone had experience with that shipping method from that website ? • Posts: 771 Threads: 5 Likes Received: 443 in 325 posts Likes Given: 209 Joined: May 2021 Reputation: 14 I can't vouch for them shipping internationally but Mouser is solid as a parts source.

I recall seeing some vendors would ship to anywhere in the world except Italy for this reason.

I recall seeing some vendors would ship to anywhere in the world except Italy for this reason. i will try to ask them @snowleopardfpv is that the correct capacitor for battery ?: https://www.mouser.it/ProductDetail/Pana...qY5NICig3w== i don't find where is indicated the voltage, but is indicated : "low esr radial leaded aluminium electrolytic capacitor" ---- I would like to buy these to have them in stock. But anyway, since I have already mounted on the wizard the capacitor that they gave me with the Racerstar Air50 3-6S 50A esc, which would be this here: https://it.aliexpress.com/item/100500204...3753%22%7D can I leave it or do I have to change it? to change it I would have to disassemble half the drone due to the fact that it is welded on the battery / esc cables and they produce a lot of heat, and it is inconvenient to work with it inside the drone • |
