But due to significant magnetic flux leakage present in the loosely wound embedded solenoid inductor structure, large inductance cannot be realized in a compact structure. This is followed by the design of a LTCC common-mode filter intended for use with USB 2.0 products. As compared to the wire-wound common-mode choke, the designed multi-layer common-mode filter produces lower insertion loss on differential-mode signal than conventional ferrite-based common-mode filter.
