· Large current (6A max.), suitable for input
connector from an AC adaptor.
· DLW5BT is designed as low profile.
· Modified its differential mode impedance higher
than other common mode choke coils, this feature
makes possible to suppress both common mode
and differential mode noise.
· DLM11GN601SD2 is ideal to keep low distortion
audio signal.
· DLM2HG can meet stereo 3 lines which contain a
ground line.
· Large current, high reliability, suitable for mortors in
automobile.

Suppression DLP/DLW Series
Example
Skew Improve Effect of Common Mode Choke Coil
Example of Skew Improvement by Common Mode Choke Coil
(Test using pulse generator waveform)
Waveform is equivalent to 1000Mbps signal
Waveform with intentionally made skew (skew: 100ps)
Skew is improved by common mode choke coil
Mechanism of Skew Improvement
Waveform rises (or falls)
Current change generates
magnetic flux on a ferrite core
Electromotive force is
generated on another line
This electromotive force works to
decrease the delay of waveform
