About the diodes. Shcottky diodes are not created equal. Some are faster than others and we want the fastest diodes we can get. FYI I just replaced my shcottky diode with TV Damper diode (BY448). I costs more than twice as much but it works just as well if not better.
Other thing about diodes is that you can safely buy low amp diode, 3 amp shottky diode can withstand over 300 amps for couple of milliseconds.
OK every man has their own opinion. And you're right ... U still can use it but if you compare to power caps from branded product (Novak, LRP, etc) then your cap is nothing compare to them. For me, I always want the best for my electronics gadgets so I don;t deal with such general / common caps or components.
For some passing weeks I try to find some info and this what I've learn so far
1. About capacitor
Check out the capacitor supply by KO Propo ... ELNA RJF series 25V 2700 μF
See the spec and you'll know what I'm talking about.
Alternatively for comparable caps with those branded products (Novak, LRP etc) you can see this site :
Another info :
1. Higher volt will have lower ESR
2. Caps put in parallel will increase the capacitance (μF) and will decrease the ESR
My reference for diode goes to this site :
It should be a schottky diode or schottky barrier/power diode, no others .....
The things you should care (as Novak said) is forward voltage (Vf) if you see in datasheet .... It should be close to zero (0,xx)
I've seen your diode spec here .... http://www.ortodoxism.ro/datasheets/philips/BY448_2.pdf
And it's in the range of common diode for Vf.
It works but it's not schottky type ....
Looking at the schottky diode which accompany the ESC (like GM Racing, Novak and others) usually it has a 30A and 25 - 40V. So I'm looking the alternative with those specs. And I found this inside my unused redundant (hot swap) PSU for computer : http://www.ortodoxism.ro/datasheets/...en/mXqwqqs.pdf
I think it's an overkill ... 40V 60A Schottky diode...and I get it for free
I'm happy with it.
I have installed and test it full-throttle unload, and so far okay.
Not try on the circuit yet (with load).... I want to know how's the braking effect
That's all about my experience for capacitor and diode... I hope it's usefull for everyone
