Common Mode Chokes (CMCs) are one of the most versatile electromechanical devices used to filter out and limit interference in power and signal transmission circuits. The SS28H-20075-CH is one of the most popular CMCs used in a variety of applications.

The SS28H-20075-CH is composed of two small cores, a high flux density magnetic core and a high permeability ferrite shell. These two components make up the core of the CMC, with two primary windings wound around them. Primary windings are the primary conductors in the CMC and they are responsible for carrying the power or signal currents. The core and primary windings of the SS28H-20075-CH are designed to have very low resistive and inductive characteristics, which allows for high current carrying capacity and minimal drop in signal quality or power loss when the CMC is used in an application.

The most common application for the SS28H-20075-CH is in power applications, such as power transmission lines, where high currents are present. CMCs are used in these cases to filter out any interference which may be present in the power line, such as electric fields or magnetic fields. This ensures that the power lines remain free from interference, which can cause signal disruption or damage.

Another application for CMCs is in signal transmission applications, where the CMC is used to limit and reduce the noise related to the signal transmission. The SS28H-20075-CH CMC is particularly effective in signal transmission applications, as its primary windings are designed to carry high signal currents with minimal signal loss.

The working principle of the SS28H-20075-CH CMC is based on the concept of mutual electromagnetic induction. This principle states that when two conductors with some relative motion between them are subjected to some external magnetic field, they will induce a current in each other. The primary windings of the SS28H-20075-CH are designed so that they are not affected by the external magnetic field, but the external magnetic field will induce a current in the two primary windings. This current will be blocked by the CMC, effectively blocking any interference potentials that may be present in the power line or signal transmission line.

In summary, the SS28H-20075-CH CMC is a versatile device used in a variety of applications, including power and signal transmission. It is composed of two small cores and two primary windings, and its working principle is based on the concept of mutual electromagnetic induction. This device can effectively block external interference in power and signal transmission lines, ensuring that the transmission lines remain free from noise and damage.
