Q.
What is a "magnetic shield type" power inductor (inductor for power circuits)?
  • Inductors (Coils)


A. The exterior of the product is covered with magnetic material. This prevents magnetic flux leakage inside the product from leaking outside. It also makes the product more resistance to external influences.
As information on shields for power inductors, TDK has published the “Selection Guide for Power Inductors in Consideration of Leakage Flux.”
