The hybrid choke coil is available as a common mode choke coil with
increased differential mode inductance. The appearance and equivalent
circuit for the PLY10 Series hybrid choke coil are shown below. The
devised structure allows the hybrid choke coils to have increased
differential mode inductance. For example, the PLY10 Series hybrid
choke coil contains 3 to 5 times larger differential mode inductance as
the previous common mode choke coil of the same size, while the hybrid
choke coil contains common mode inductance equivalent to that of the
previous common mode choke. In other words, differential mode noise can
effectively be suppressed as well as common mode noise, simply by
replacing the previously used common mode choke coil with the PLY10
Series. This cuts the number of components and mounting area in half,
compared to adding another differential mode choke coil or common mode
choke coil on the circuit. |
