We provide an introduction of the FW series three-phase common mode choke coil SPICE model.
AEC-Q200 is a test standard for certifying the reliability of passive components. It specifies the testing requirements and test quantities for each component.

Note that the lead wire may not be subject to excess force and also may not be bent repeatedly because the wire is made of copper.
For actual measurements of a noise filter using the common mode choke coils and the SPICE simulation, we apply a model using coupling coefficient k for the magnetic coupling characteristics of the common mode choke coils.
Here, we check the attenuation effect of normal mode noise in a filter circuit in a comparison of actual measurements and simulation for a noise filter using a common mode choke coil.
Here, we check the attenuation effect of common mode noise in a filter circuit that compares the actual measurements and simulations of a noise filter using a common mode choke coil.
Compared to a solenoid coil, the merit of a toroidal-type magnetic body is its ability to produce large inductance under the same conditions.Compared to a solenoid coil wrapped, which is a bar-shaped magnetic body with a conductive wire wound around it, the magnetic flux of a toroidal coil, which is a magnetic body with a closed loop, is confined within the core, so almost no magnetic flux leaks outside the core.
Replacing electrical characteristics equivalent to those of the ferrite choke coil specifications with the nanocrystalline coil FL-V series, offers the advantages of "downsizing", "low DCR" and "low stray capacitance".
In this document, we validated the effect of the attenuation characteristics of an LC filter (low-pass filter) using our amorphous magnetic SM coil and conductive polymer hybrid aluminum electrolytic capacitor for the purpose of suppressing high-frequency noise in DC power lines.
When constructing equivalent circuits for common mode choke coils, the numerical value of the equivalent circuit is calculated mainly by performing measurements in three steps (STEPs 1 to 3).
