Inductor values can be determined mainly in two ways, namely text coding, and color coding methods. Some inductors are larger in size, thus often their values are printed on their body (nameplate details).
However, for smaller inductors, abbreviation or text is used because there may not be enough room, for printing the actual value on it. Also, some inductor values can be determined by reading the color on the body of inductors by comparing them with a color coding chart.
- Color Rings: The first two of these represent a two-digit significant number. The third band represents the multiplier. The inductance is calculated by multiplying the significant number by ten by the power of the value of the third band. The fourth band represents tolerance.
- Small inductors having high Q and low distributed capacity. Excellent for use where space, weight, and size is a factors.
- Axially leaded inductors with a 10% tolerance are suitable for a wide range of applications including decoupling, filtering, and RF blocking.
- These fixed inductors are coated with epoxy resin ensuring humidity resistance for long life. A fixed inductor uses multiple coils of a conducting material to store energy using a magnetic field.
- Low current and low power are made in molded cases resembling resistors. These may be either plain (phenolic) core or ferrite core. An ohmmeter readily distinguishes them from similar-sized resistors by showing the low resistance of the inductor.
- Maximum DC Current:2.52DC A (max)
- Self Resonant Frequency:6.5Hz/0.25V
- Body Size:3x8mm
These ring inductors are a pleasure to work with. They are easy to use and work as expected. Thanks guys.
