Standard Series

Shown here are typical common mode fre-

quency plots of each part number. The plots

indicate the relative performance of each part

over the frequency range of most interest for

designers of equipment that must meet FCC

and VDE noise regulations. It is important to

note that only a common mode signal will

be attenuated as shown. Differential mode

power such as 50/60 Hz power line currents

or data signals will pass through unimpeded

by the common mode impedance.The inser-

tion loss for differential signals is shown in

the lower graph. These data were taken in a

50 Ohm system. All parts should be tested

using an appropriate Line Impedance Sta-

bilization Network (LISN) when testing EMI/

RFI performance of off-line power converters.
