●

Impedance is not lowered by current superposition (Current at 20A or less) because of higher saturation magnetic

flux density compare to ferrite. Possible to suppress normal-mode noise.

●

Due to higher Curie temperature material, it enables stable temperature characteristics under condition of -40 °C

to +85 °C, which does not allow impedance to be lowered.

●

Resin-coated surface of the core, preventing its edge from damaging cables.
