BOXEE BOX media player

[notwired]

Device: 1st gen. Boxee box (the oddly shaped box)


Opened the box after a laud bang (the media player was still stable in use - no hangs or freezes).

As you can see in pic, even the capacitor housing took damage after being ejected violently

Please some help identifying the blown cap manufacturer (logo is a S inside a C) and a suitable replacement.

Elite CS Cap 180uF 16v 12mOhm impedance/esr , 4800mA ripple.



Any good polymer capacitor will work for that. If you have some faulty motherboard or video card with a 220-270uF 16v capacitor on it, you could use that, I don't think the actual capacitance is so strict.

But do use low esr polymers, not electrolytics. Electrolytics at such low capacitance have too high esr.

Re: BOXEE BOX media player

just to be sure i would check the power supply to make sure it is within spec.
even with cheaper brands of polys this is rare.if ok replace all others like it.
doing torture tests of polys i noted most would take double the rated voltage without failing.at 3x they would go bang like yours.
i dont expect elite to have anywhere near that high of a margin though. mine were fujitsu,ncc,sanyo

Re: BOXEE BOX media player

Just found and bought some yageo SX series 220uf 16V.
The datasheet doesn`t tell me too much but it says low esr.

But i will be on the look for a good polymer capacitor.

Thanks for the help !

Re: BOXEE BOX media player

Theoretically, that Yageo is NOT good enough.

It has 410mA ripple, 330mOhm impedance/esr. It's about 10-20 times worst than the Elite cap (with 4800mA ripple, 12 mOhm impedance/esr).

And like kc8adu says, do check the power supply as well.
