Re: Xbox 360 blown caps
No, 820uF is too low. 1800uF 4v would be acceptable. May be pushing it but 1500uF 4v may also work (I wouldn't do it)

Re: Xbox 360 blown caps
Replace with electrolytic capacitors that are very low ESR (Panasonic FM/FR , UCC KZE series) or polymer capacitors.
In the case of the capacitors closest to chips (output of VRM) it's safe to use...

Re: Help with capacitor substitution for a DVR
I sincerely doubt you need so high end capacitors.
Most likely it was some overstock capacitors they had, or someone used them instead of other capacitors.
I mean, you typically need these ultra...

Re: Adhesive to Hold on LED Strips?
Problem is you don't know how well those tapes transfer heat into the metal back side of the lcd/tv panel ... the led strips probably use the back metal to spread led heat.
You can use thermal...

Re: Zero to Expert in pcb design
Nobody does that, because nothing's smart enough to automatically figure out the number of layers a PCB has, and x-ray capability to figure out traces within internal layers.
Also, big components...

Re: Asus GTX 980ti Matrix capacitor
It's a polymer capacitor, so the ESR will be very small. The video card receives 12v and 3.3v through the pci-e slot and pci-e power connectors.
The capacitance being so low at 150uF, I would...

Re: Capacitor replacement
Have to agree, the small one may not be able to handle the current.
Look into capacitors rated for higher voltage, like for example 35v..63v.. the higher volume will give them the ability to...

Re: Nippon Chemi-Con 3300uF 10x25mm?
I sincerely doubt it. You should be fine with KZE.
Also keep in mind if they're for 3.3v and 5v output filtering, you'll be fine with 6.3v rated KZE (or FM) which will have slightly higher esr......

Re: Zero to Expert in pcb design
Depends on your needs. For some niches some tools are better than others.
For simple boards, KiCad, DipTrace, even Eagle could be good enough.
For more complex stuff, there's other players in...

Re: CHEMI-CON 4700uF AH Alternatives ?
More modern series of capacitors will be often smaller for the same capacity and voltage rating, so you can also choose to go with 63v rated capacitors (next voltage rating above 50v)

Re: Nippon Chemi-Con 3300uF 10x25mm?
Yeah, KZE series has a bit too low ESR for switching power supplies, but it should still work if it's not a crappy psu in the first place.
10mm KZE while not in datasheet is not necessarily...
