Replacing a cap in my son's Casio keyboard

[TehCapNoob]

Hi all,

I know almost nothing about capacitors... or for that matter about electronics in general, so please be kind.

The other day my son connected his brother's 9V Casio keyboard to a 24V power source. He played one note and it went BANG! and a little puff of smoke came out.

I took it apart and found one of the caps on the circuit board had exploded. From the shreds of the plastic wrapper I managed to see that it was a Samxon GS(M), had a capacitance of 220 uF and a temperature of 85°. I can't see what the voltage was though. The other caps on the board have different voltages - 16V, 10V or 6.3V - so I can't really draw any conclusions from that. The cap was 12mm high by about 6.5mm in diameter.

I talked to a guy here at work who knows a little about electronics, and he suggested replacing it with a Yageo 220 uF 35V (105°) cap, 12mm high by 10mm in diameter.

Can anyone confirm if this might work? Don't the voltage and temperature requirements also have to match the original cap?

Thanks in advance

Ray

it will probably work fine.
if it works and no other damage hide that 24v psu!

Thanks for the quick reply.

He knows now to make sure the voltage matches lol.
