Check the listing for details. 25PC 0410 Color Ring Inductor 10uH 0.5W Axial RF Coil Inductor. Condition: New. Listed at 17.77 USD. features: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 to the power of the value of the third band. The fourth band represents the tolerance.Small inductors having high Q and low distributed capacity. Excellent for use where space, weight and size is a factor.Axially leaded inductors with a 10% tolerance suitable for a wide range applications including decoupling, filtering and RF blocking.These fixed inductors are coated with epoxy resin ensures humidity resistance for long life.Fixed inductor uses multiple coils of a conducting material to store energy using a magnetic field.For low current and low power are made in cases resembling resistors.
