Code 473 passes the supported grammar: first digit 4, second digit 7, multiplier 3. Keep 47 together, multiply by 10³ pF, and convert the exact result without moving the decimal in the wrong direction.
Calculate 47 × 10³ pF
10³ is 1000. Multiplying 47 × 1000 gives exactly 47000 pF. The third digit supplies three zeros; it is not another significant digit and it does not encode tolerance.
Convert 47000 pF to 47 nF and 0.047 µF
47000 pF ÷ 1000 = 47 nF. Dividing by 1000000 gives 0.047 µF. These are exact decimal forms of one nominal capacitance, not rounded measurements.
Do not infer the rest of the marking
A following letter or nearby number may belong to a family-specific tolerance, voltage, dielectric, date, or other field. CapCode intentionally stops after the three digits; use the exact manufacturer document for every additional symbol.
