Beginning of Winding
High-frequency noise can pass through the
Filter easily because both edges of coils are
close as shown above

Beginning of Winding
High-frequency noise can hardly pass
through the Filter because both edges
of coil are not close as shown above
Standard Winding
Large inductance is available
→Highly Efficient in Low Frequency
Sectional Winding
Excellent performance in high frequency
Stray capacity between windings is low
