The first two bands represent significant digits, the third band indicates the multiplier, and the fourth band (if present) denotes tolerance. For example, a color code of red, orange, and brown would represent an inductance value of 3.1 µH (3.1 followed by one zero). 2. **Standard Color Code Chart**: The standard color code chart is essential for decoding the values represented by the colors. The colors and their corresponding values are as follows: - Black: 0 - Brown: 1 - Red: 2 - Orange: 3 - Yellow: 4 - Green: 5 - Blue: 6 - Violet: 7 - Gray: 8 - White: 9 3. **Differences Between Inductors and Resistors in Color Coding**: While both inductors and resistors use color coding, the interpretation differs. Resistors measure resistance, while inductors measure inductance. The color coding for inductors may also include additional bands to indicate the type of core material or the inductor's quality factor (Q). III. Mainstream Models of Color Coded Inductors A.
