📖 THT Capacitor Code Guide
3-Digit Code (most common)
First 2 digits = significant figures, 3rd digit = multiplier (power of 10). Result is in pF.
104 → 10 × 10⁴ = 100,000 pF = 100 nF = 0.1 µF
222 → 22 × 10² = 2,200 pF = 2.2 nF

Direct Marking (small values <100 pF)
Values under 100 pF may be printed directly: 47 = 47 pF, 10 = 10 pF.
Decimal notation: 4p7 = 4.7 pF, n47 = 0.47 nF.
Values under 100 pF may be printed directly: 47 = 47 pF, 10 = 10 pF.
