Capacitor Color Codes for Identification Chart
Capacitors may be marked with 4 or more colored bands or dots. The colors encode the first and second most significant digits of the value, and the third color the decimal multiplier in picofarads. Additional bands have meanings which may vary from one type to another. Low-tolerance capacitors may begin with the first 3 (rather than 2) digits of the value. It is usually, but not always, possible to work out what scheme is used by the particular colors used. Cylindrical capacitors marked with bands may look like resistors.

Black Brown Red Orange Yellow Green Blue Violet Grey White Gold Silver Extra bands on ceramic capacitors will identify the voltage rating class and temperature coefficient characteristics. A broad black band was applied to some tubular paper capacitors to indicate the end that had the outer electrode; this allowed this end to be connected to chassis ground to provide some shielding against hum and noise pickup.
Polyester film and 'gum drop' tantalum electrolytic capacitors are also color-coded to give the value, working voltage and tolerance.

A common question when looking at ceramic capacitors is what do the temperature coefficient numbers/letters mean? These numbers will generally break down to a temperature range and the variation in capacitance over that specific range. The first thing you need to understand with what standard and class you are looking at. These are split between the International Electrotechnical Commission (IEC) and the Electronic Industries Alliance (EIA)
Capacitor Code Charts
Here is a chart on the different classes and definitions:
| IEC/EN 603841 & IEC/EN 60384-8/9/21/22 | EIA RS-198 |
|---|---|
| Class 1 ceramic caps offer high stability and low losses for resonant circuit applications | Class I ceramic caps offer high stability and low losses for resonant circuit applications |
| Class 2 ceramic capacitors offer high volumetric efficiency for smoothing, by-pass, coupling and decoupling applications | Class II (or written class 2) ceramic capacitors offer high volumetric efficiency with change of capacitance lower than −15% to +15% and a temperature range greater than −55 °C to +125 °C, for smoothing, by-pass, coupling and decoupling applications |
| Class 3 ceramic capacitors are barrier layer capacitors which are not standardized anymore | Class III (or written class 3) ceramic capacitors offer higher volumetric efficiency than EIA class II and typical change of capacitance by −22% to +56% over a lower temperature range of 10 °C to 55 °C. They can be substituted with EIA class 2- Y5U/Y5V or Z5U/Z5V capacitors |
| Class IV (or written class 4) ceramic capacitors are barrier layer capacitors which are not standardized anymore |
With class definitions understood you can look how the temperature coefficients break down.

Smd Capacitor Code Chart
Looking at these charts you see, an “NP0” capacitor with EIA code “C0G” will have 0 drift, with a tolerance of ±30 ppm/K, while an “N1500” with the code “P3K” will have −1500 ppm/K drift, with a maximum tolerance of ±250 ppm/°C.
Note that the IEC and EIA capacitor codes are industry capacitor codes and not the same as military capacitor codes.

Class 2 per EIA RS-198
| Letter Code for Low Temp | Number Code for High Temp | Letter code for change of capacitance over the temp range |
|---|---|---|
| X = −55 °C (−67 °F) | 4 = +65 °C (+149 °F) | P = ±10% |
| Y = −30 °C (−22 °F) | 5 = +85 °C (+185 °F) | R = ±15% |
| Z = +10 °C (+50 °F) | 6 = +105 °C (+221 °F) | S = ±22% |
| 7 = +125 °C (+257 °F) | T = +22/−33% | |
| 8 = +150 °C (+302 °F) | U = +22/−56% | |
| 9 = +200 °C (+392 °F) | V = +22/−82% |
For instance, a Z5U capacitor will operate from +10 °C to +85 °C with a capacitance change of at most +22% to −56%. An X7R capacitor will operate from −55 °C to +125 °C with a capacitance change of at most ±15%.
Here are some common Class 2 configurations:
- X8R (−55/+150, ΔC/C0 = ±15%),
- X7R (−55/+125 °C, ΔC/C0 = ±15%),
- X6R (−55/+105 °C, ΔC/C0 = ±15%),
