Common Mode Chokes are used in power supply circuits for filtering in a wide range of electronic products. Although ubiquitous, their function and basic operation is often poorly understood.
To understand how a CMC works, one must first understand the difference between common mode noise and differential mode noise and then how the non-ideal elements of a CMC impact them. One common misconception is that only the inductance should be maximized to best filtering. In practice, it is critical to maximize inductance but also equally important to minimize parasitic series resistance and winding capacitance. In our white paper simplified equivalent circuits are used to model graphically and mathematically how each element in the common mode choke impacts it’s impedance versus frequency curve, and consequently filtering performance.
Pulse offers common mode chokes in several constructions, the following products are new: PAC6006.XXXNL EP13, PA5140.XXXNL EP18 and PA5141.XXXNL EP22 platforms.
