Cap values problem

[tazman]

Hi - I have two caps and am having a heck of a time figuring out their values.  Could anyone help?

1)    u(as in micro)22 K100  (Not sure of Brand)
2)    0.15 100-B1  (WIMA)


Thanks,

Rob

The first one. 22K is short hand for 22,000. So your looking at a 22000pF cap that is rated for max 100V. 22,000pF = 22nF = .022uF



Second one should be .15uF...

I think the "K" is the tolerance code and means +/- 10% and it's not used as a multiplier in this case.

The u22 means .22uF.  It's the Euro numbering system.  Check this chart under "Euro."

When in doubt, pull it out of the circuit and measure it.
