Common
Can Be Installed In A Two Turn Configuration To Mulitply Impedance
Can Be Used In 3 Phase Applications
The Series 45 Common Mode Arrays offer compact filtering of common mode noise in applications carrying up to 10 amps
continuous current. This product series provides the flexibility of filtering 3-phase power supply without impact on common
mode filtering performance, as all conductors share a common magnetic circuit. Additionally, the 4-line array can be
configured to offer over 500 W peak impedance for a normal 2-line circuit. Both Thru-Hole (B) & Surface Mount (R) versions
available.
