What's the value written on this capacitor?
« on: July 27, 2016, 05:10:29 am »
Hi, I'm trying to repair a pc motherboard and I have to replace 3 electrolytic capacitors labeled "FP 13Bx 101 16" but I don't know how to read that :\  Maybe someone here can help me

Thanks

Are they aluminum types? If so, I would say 10uF 16VDC. A picture would be helpful.

I think 101 is more like 100uF

Hi, thanks for the reply. Here you have a picture . As you can see it's aluminum. I also believe that is 10uf 16VDC. Can you confirm that by seeing the picture? Thanks

Maybe it's helpful to say that those 3 capacitors were located close to the I/O port usb ports. The motherboard is an Asus P8P67 rev 3.1 if that helps

Looks like 100uF, 16V.  Might be Panasonic FP series, but the markings don't match what's shown in the data sheet Mouser currently links to.  It may be an older cap and they've changed the markings, or it may be a different manufacturer/series.  It does look like 100uF @16V, though, whoever made it...

The marking is typically digit-digit-multiplier.  Think of the multiplier simply as the number of zeroes to put after the digits.  In your case, 1-0-with one additional zero for 100uF.  471 would be 470uF (4-7-with one additional zero), 1000 would be 102 (1-0 and two more zeroes) and 100 would be 10 (1-0-with zero additional zeroes resulting in 10uF)

It gets a little weirder when they're values with a decimal; those are typically displayed with an 'R' where the decimal point would be, thus still giving a three digit code.  For instance, 2.2 uF would be shown as 2R2, and 0.47uF as R47.

Hope this helps.

If it jams, force it.  If it breaks, you needed a new one anyway...

Thanks, I'll replace it with 100uF 16V capacitors.
