                  TOROID COILS
FEATURES
 l Enables you to make compact dummy choke coils for greater efficiency.
 l Less power loss and minimum thermal effect to peripheral components.
 l Perfectly matched to power supplies where average power and peak power differ greatly, with
    magnetic saturation kept minimum.
 l Low radiation noise based on its toroidal construction.
 l Various materials can meet with a wide range of frequency requirement.

APPLICATIONS
l Computers, Power supply, EMI/RFI Suppression and Wideband choke coils.
