Q.
Which inductor is recommended for smoothing a power circuit?
  • Inductors (Coils)


A. Loss has a direct effect on the efficiency of the power supply. Consequently, we recommend that selecting a product with low coil loss (DC resistance and AC resistance at the operating frequency). However, this is only intended as an estimate, so please confirm the product with actual machinery before use. Also, please use the core loss calculation tool that TDK has made available through SIM CAL STUDIO. For other product inquiries, please send inquiries to your nearby sales office or distributor, or send inquiries from this website.

There are direction identification markings on some products. What are those markings for?
Q.
Since it seems that inductors for high frequency circuits uses dielectric ceramics as the their material, I am concerned about magnetic flux leaking out.

I do not understand how the direction identification markings on the MLG/MHQ series inductors correspond to each other.
