Capacitance is read in picofarads (pF)

 Capacitance is read in picofarads (pF)



For a five-band capacitor


1st band: First significant digit

2nd band: Second significant digit

3rd band: Multiplier — number of zeros to add

4th band: Tolerance

5th band: Rated working voltage

Color → Digit

Color Digit

Black 0
Brown 1
Red 2
Orange 3
Yellow 4
Green 5
Blue 6
Violet 7
Gray 8
White 9

Common Tolerance Codes

Green: ±5%

White: ±10%

Voltage Codes Shown in This Scheme

Red: 250 V

Yellow: 400 V

Reading Examples

Red – Red – Orange – Green – Red
22 × 1,000 pF = 22 nF
Tolerance: ±5%
Voltage rating: 250 V

Orange – White – Red – White – Yellow
39 × 100 pF = 3,900 pF = 3.9 nF
Tolerance: ±10%
Voltage rating: 400 V

Brown – Black – Orange – White – Yellow
10 × 1,000 pF = 10,000 pF = 10 nF
Tolerance: ±10%
Voltage rating: 400 V

Yellow – Violet – Orange – White – Red
47 × 1,000 pF = 47,000 pF = 47 nF
Tolerance: ±10%
Voltage rating: 250 V

Important: Capacitor color-code conventions can vary by capacitor type and coding system, so the component's datasheet or manufacturer marking should be used when available.

I corrected the “240 V” shown in the supplied image to 250 V for the red voltage band, because the referenced capacitor color-code tables identify red as 250 V in this coding scheme.
