Common mode choke coils are characterized by the fact that impedance drops at high frequencies.
This document explains the SPICE MODEL of the FW,FL-V series of common mode choke coils.
We adopted a new model concept to bring the frequency dependence of the impedance characteristics closer to measured values.
The magnetic coupling characteristic of common mode choke coils is that even though the primary and secondary sides of the coil are electrically insulated, the magnetic flux generated in the core flows through both the primary and secondary coils. This is a phenomenon in which voltages are mutually induced according to changes in magnetic flux.
Noise generated in power supply circuits includes normal mode noise and common mode noise, with the direction of the magnetic field generated differing depending on the noise current.
Normal mode noise is a mode in which noise returns to the noise source from the positive side of the power supply via the negative side. Common mode noise is a mode in which noise with the same phase on the positive and negative sides of the power supply travels in the same direction and returns to the noise source via the ground.
Our Inductors (Coils/Cores) in production are RoHS2 Directive compliant.
Nanocrystalline are soft magnetic materials that have nano-sized crystals in amorphous alloys.
On a Common Mode Choke Coil, the ratio of turns around the primary and secondary windings are equal(L1=L2), and the polarity of the windings (the direction of the windings) are the same.
