ERSE .20mH 18 AWG Air Core Inductor

ERSE manufactures the finest audio coils in the world today.

This is a bold statement, but here is the explanation directly from ERSE: With our 42 years of experience we are confident that you will not find a better audio coil anywhere. Don't settle for off brand or copies for your speaker project. Quality coils begin with quality components. All of our inductors offer our PURITY GUARANTEE. This states that we will not manufacture any coils unless the copper wire is 99.9% pure and meets the criteria of oxygen free. Our wire is made from CDA 101 copper cathode and coated with an insulating enamel to insure musical accuracy. This is our guarantee.

The wire is then wound with perfect layer construction methods using highly precise orthocyclic computerized coil winders that maintain the crystalline structure of the wire. This process keeps tolerances well within 3% or less during the entire winding process and eliminates saturation and hysteresis distortion. The precision tension control insures that we do not stretch or harm the crystalline structure of the copper cells within the wire. Every single coil is exactly the same due our precise layering control and hysteresis tension. Experience the difference of uncompromising quality on your next audio speaker project.
