Off-the-shelf “flying lead” and surface mount broadband conical inductors, Figure 1 and Figure 2, are a special type of broadband RF choke that are used to filter radio frequency (RF) and microwave frequency interference from electronic circuits. At high frequency, the RF choke becomes a high impedance element used to isolate noise or DC from desired signals.

The WE-PD-family storage chokes are ideal for integrated DC/DC converters and switching controllers with output powers from 0.01 W to 300 W. The inductors help to raise the efficiency of switching controllers to over 95 percent. Whereas the “Standard” and “Robust” series have a NiZn core, the “Performance” variant with MnZn attains even higher saturation current values for the same component size.
