Inductance Color Code app for iPhone and iPad

Inductance is one of the most common and fundamental electronic components. The function of inductance is to generate a magnetic field, which passes through low frequencies and resists high frequencies. Therefore, inductors are often used in electronic circuits for filtering, energy storage, and oscillation.

The labeling of the Inductance Color Code is the same as the color ring resistance. The size of the volume can distinguish the size of the current that can pass through. Because the usage environment of inductors varies greatly, it is impossible to calculate all the inductance requirements in one way, with a specially designed design for specific environments. Small inductors are only as big as sesame seeds, while large inductors are as big as trucks.

How to identify the Inductance Color Code and determine its quality?
Identification method of color ring inductance
1. The numbers represented by the color of the inductor in the color ring: brown 1, red 2, orange 3, yellow 4, green 5, blue 6, purple 7, gray 8, white 9, black 0
The magnification represented by the colors of the color ring inductance: brown * 10 (10 ^ 1), red * 100 (10 ^ 2), orange * 1K (10 ^ 3), yellow * 10K (10 ^ 4), green * 100K (10 ^ 5), blue * 1M (10 ^ 6), purple * 10M (10 ^ 7), gray * 100M (10 ^ 8), white * 1000M (10 ^ 9), black * 1 (10 ^ 0), gold * 0.1 (10 ^ 1), silver 0.01 (10 ^ 2)

The error levels represented by the color of the color ring inductance are: gold 5 [%], silver 10 [%], brown 1 [%], red 2 [%], green 0.5 [%], blue 0.25 [%], purple 0.1 [%], gray 0.05 [%], and the basic unit of the colorless color ring inductance is "micro heng".

Inductance Color Code can greatly improve work efficiency and reduce unnecessary work for electronic engineers.
