How to read: The first two bands are the significant digits, and the third band is the multiplier (10ⁿ in pF).

Note: EIA 3‑digit codes and color bands are only defined for small ceramic capacitors, typically in the range of 10 pF up to about 9.9 µF. Larger values (like electrolytics) are not marked with these codes, so the calculator shows N/A (out of range) in those columns.
