RESEARCH & DEVELOPMENT
The total volume can then save over 54% and flat wire common
mode choke comes with 1.2x the power density of the traditional
T-core. From the electrical result, with the same level of inductance, flat wire common mode choke offers lower DCR and higher
current level. The impedance curves on Fig. 15 also show the flat
wire common mode choke offers higher impedance with higher
frequency.

CONCLUSION
In conclusion, the impedance becomes much more important in
the common mode choke design at higher frequency. By looking
at a number of different winding techniques and flat wire vs round
wire comparisons, the flat wire with rectangular core body common mode choke shows its best result at the following:
I. Fully automatic high precision winding machines insure competitive costs.
II. The singles-layer winding design lowers the parasitic component and provides better performance at higher frequencies.
III. The lower distributed capacitance means a higher performance
at higher frequencies.
IV. The lower DCR means better thermal performance.
V. The higher power density results in up to 50% space saving.
VI. The higher reliability results in extended product life time.
