The capacitor is most likely rated in picofarads. The 'k' just means it =
has a 10% tolerance. The last digit before the 'k' is a power of ten. =
For example,

152k would mean "15X10^2 picofarads, +- 10%.

Tappers,

Reading capacitor labels is a strange art. Is anyone skilled at =
reading ceramic capacitor labels?

I have a question about reading the value of a ceramic capacitor. A =
small ceramic capacitor typically has a capacitance value in the range =
of pico Farads, I thought. But it is labeled either with just a number =
and no indication of pico, nano, or micro range, or it is labled with a =
symbol k, which I think stands for pico? =20

Does anyone know?

I don't have a capacitance meter, I am too lazy to grab my Horowitz =
and Hill and I don't want to set up a tuned LCR resonance circuit to get =
the value. I just want to know how to read the label.


Thanks, from snowy and windy RI.
