Helical air core coils

Flat Helical windings are popular in application where a high stacking ratio is required. It has good thermal properties and low skin effects in high frequency applications due to large surface area and shallow skin depth. It is commonly used in high current inductors, common mode chokes, differential mode chokes, power factor correction inductors and transformers. Other application includes motor windings, etc.
