# 🎨 Electronic Component Color Codes
## 📖 Introduction
Color codes are used on various electronic components, most notably resistors, capacitors, and inductors, to indicate their value, tolerance, and other important specifications. This system allows for easy identification of component ratings in compact formats. Below is a guide to understanding how to interpret color codes for these components.
---
## 1. **Resistor Color Code**
Resistors often use a series of colored bands to represent their resistance value and tolerance. The most common scheme is the **4-band** and **5-band** color code system.
### 📏 **4-Band Resistor Color Code**
The **4-band** code is the simplest and consists of:
- **Band 1**: First significant digit
- **Band 2**: Second significant digit
- **Band 3**: Multiplier (number of zeros)
- **Band 4**: Tolerance
| **Color** | **Digit** | **Multiplier** | **Tolerance** |
|------------|-----------|----------------|-----------------|
| Black | 0 | 1 | |
| Brown | 1 | 10 | ±1% |
| Red | 2 | 100 | ±2% |
| Orange | 3 | 1,000 | |
| Yellow | 4 | 10,000 | |
| Green | 5 | 100,000 | ±0.5% |
| Blue | 6 | 1,000,000 | ±0.25% |
| Violet | 7 | 10,000,000 | ±0.1% |
| Gray | 8 | | ±0.05% |
| White | 9 | | |
| Gold | | 0.1 | ±5% |
| Silver | | 0.01 | ±10% |
### 📏 **5-Band Resistor Color Code**
The **5-band** code is used for more precise resistors, and the format is:
- **Band 1**: First significant digit
- **Band 2**: Second significant digit
- **Band 3**: Third significant digit
- **Band 4**: Multiplier
- **Band 5**: Tolerance
| **Color** | **Digit** | **Multiplier** | **Tolerance** |
|------------|-----------|----------------|-----------------|
| Same as 4-band for digits and multiplier, additional third significant digit. | | | |
---
## 2. **Capacitor Color Code**
Capacitors may also use color codes to indicate their capacitance value and tolerance, though the system is less commonly used today due to the shift to printed markings.
| **Color** | **Digit** | **Multiplier (pF)** | **Tolerance** |
|------------|-----------|---------------------|----------------|
| Black | 0 | 1 | ±20% |
| Brown | 1 | 10 | ±1% |
| Red | 2 | 100 | ±2% |
| Orange | 3 | 1,000 | ±0.5% |
| Yellow | 4 | 10,000 | ±0.25% |
| Green | 5 | 100,000 | ±0.1% |
| Blue | 6 | 1,000,000 | ±0.05% |
| Violet | 7 | | |
| Gray | 8 | | |
| White | 9 | | |
### **How to Read a Capacitor Code**
- **First Band**: Represents the first digit.
- **Second Band**: Represents the second digit.
- **Third Band**: Represents the multiplier.
- **Fourth Band**: Represents tolerance.
---
## 3. **Inductor Color Code**
Inductors can also use a similar system to resistors, with color bands representing inductance values (in microhenries, μH) and tolerance.
| **Color** | **Digit** | **Multiplier** | **Tolerance** |
|------------|-----------|----------------|-----------------|
| Black | 0 | 1 | |
| Brown | 1 | 10 | ±1% |
| Red | 2 | 100 | ±2% |
| Orange | 3 | 1,000 | |
| Yellow | 4 | 10,000 | |
| Green | 5 | 100,000 | ±0.5% |
| Blue | 6 | 1,000,000 | ±0.25% |
| Violet | 7 | 10,000,000 | ±0.1% |
| Gray | 8 | | ±0.05% |
| White | 9 | | |
| Gold | | 0.1 | ±5% |
| Silver | | 0.01 | ±10% |
---
## 4. **Other Component Color Codes**
Some other passive components like **diodes** and **varistors** may also utilize color codes, though they are often indicated with simpler markings or are directly printed with their values.
---
## 🧮 **Online Color Code Calculators**
To quickly decode resistor or capacitor values based on their color bands, you can use the following online tools:
1. **[Resistor Color Code Calculator](https://www.allaboutcircuits.com/tools/resistor-color-code-calculator/)**: Input color bands to find the resistance value.
2. **[Capacitor Code Calculator](https://www.digikey.com/en/resources/conversion-calculators/conversion-calculator-capacitor-code)**: Calculate capacitance based on code.
---
## 📘 Conclusion
The color code system is a quick and effective way to identify the values of resistors, capacitors, and inductors. By understanding the meaning of each color band, engineers and hobbyists can easily determine the component's ratings without needing additional tools. These color codes remain essential knowledge for anyone working with electronic components.
