What is inductor color coding?

## Understanding Inductor Color Coding.

Inductor color coding is a method used to identify the value and tolerance of an inductor component. This is similar to resistor color coding, but the color bands on an inductor represent different values and tolerances.

### Step-By-Step Guide.

1. **Examine the Color Bands:** Inductors typically have 4 or 5 color bands on them. These bands represent the inductance value and tolerance of the inductor.

.

2. **Decode the Color Bands:** Each color band corresponds to a number or a multiplier. The first two bands represent the first and second digits of the inductance value. The third band represents the multiplier, while the fourth band indicates the tolerance.

.

3. **Color to Value Conversion:** Use a color chart to convert the colors to their corresponding values. For example, black is 0, brown is 1, red is 2, and so on. The multiplier band color will determine the number of zeros that follow the first two digits.

.

4. **Calculate the Value:** Combine the first two digits with the multiplier to calculate the inductance value in microhenries (μH). For example, if the first two bands are brown (1) and black (0), and the multiplier band is orange (3), the inductance value would be 10 x 10^3 = 10,000 μH.

.

5. **Determine the Tolerance:** The fourth band indicates the tolerance of the inductor. Common tolerance values include ±1%, ±5%, and ±10%. The tolerance band can be silver, gold, or other colors depending on the tolerance level.

.

6. **Check for Manufacturer Specific Codes:** Some manufacturers may use their own color coding schemes, so it's essential to refer to their datasheets for accurate information.

.

### Conclusion.

Inductor color coding is a useful method for identifying the value and tolerance of inductors quickly. By understanding the color bands and their corresponding values, you can easily determine the specifications of an inductor component for your electronic circuit designs.
