How to read a three-digit capacitor code
Treat the first two digits as the significand and the third as the number of zeros in a picofarad value.

Three-digit codes, exact units, and strict limits
Three guides explain the pF multiplier, exact pF/nF/µF conversion, and why three digits cannot identify tolerance, voltage, dielectric, polarity, or a complete component.
Convert pF, nF, and µF without losing a factor of 1000
Anchor the code in picofarads, then move exactly between pF, nF, and µF using factors of 1000.

Separate nominal capacitance from tolerance, voltage, dielectric, polarity, construction, and safety information.
