Q.There are direction identification markings on some products. What are those markings for?
Inductors (Coils) > Inductors (Coils) > Inductors (Coils)
An inductor has a winding direction (polarity), and the marking is placed so that the polarity can be confirmed from its external appearance.
Depending on usage conditions, the polarity of the inductor can affect the inductor's characteristics.
TDK offers Search by Characteristics to help you search for the products that do not have winding direction.
