Common mode chokes (or filter chokes) are one of the most effective methods for EMI filtration of power and signal lines. Fule Electronics offers many standard common mode choke products that meet the demand of typical circuit applications. We also standard products will not meet all requirements of a particular application, so we offer a wide variety of custom options for common mode chokes, providing the very best solution for the circuit applications.

The common mode choke filters the common mode EMI currents without causing signal degradation and without derating under high currents. Fule Electronics has designed their standard common mode chokes to work over a wide frequency range and to provide the highest common mode impedance. Stable common mode chokes allow most signals to pass unaffected, yet filter the noise (EMI) from these circuits.

Surface Mounting

Fule offers several surface mount common mode chokes that are used in the following applications:

• DC to DC Converters

• Notebook Computers

• Digital Cameras

• AC Adapters

• LCD Displays

• Counter measure for EMU of USB - IEEE 1394

Printed Circuit Board Mounting Common Mode Chokes

Fule offers several lines of through hole application common mode chokes that offer excellent characteristics such as:

• Winding constructions that presents the highest self resonant frequency

• Constructions that will meet your requierments for either low profile or minimal board space consumption

• Excellent flame retardant characteristic in the mounting header of the toroidal style CMC - UL94VO

• Customization of these products is available.  Our engineers will work along side of you to customize a product to meet your requirement

Common mode chokes are applied to pairs of conductors the supply path and the return path. Our standard common mode chokes are effective in filtering supply and return conductors with in-phase signals of equal amplitude. In many applications common mode chokes are coupled with Power Factor Correction (PFC) components.

 Fule Electronics common mode chokes are designed to meet applications requiring a high DC current bias and are compatible with switch-mode power supply designs. We also offer differential mode inductors for filtering out-of-phase or uneven amplitude signals.

Many IC reference designs use Fule Common Mode Inductors as well as Switchmode Transformers, Current Transformers, Power Factor Correction Inductors and Power Inductors.
