Common Mode Chokes, such as DFSG-20-0002, are a form of technology used in power supplies, designed to filter out high-frequency noise or "spikes," so that electric signals remain stable. The way in which the device works is by creating an inductive field in order to block any high-frequency noise, keeping the signal flowing in a certain direction.

The basic construction of the DFSG-20-0002 is an inductive coil, or choke, wound around a core. The core is typically made of metal, such as iron or ferrite, and is typically surrounded by insulating material. The choke creates a magnetic field that blocks the high-frequency electrical noise from entering the power supply, preventing the signal from deteriorating. The choke also serves to reduce any noise generated by the power supply itself.

A common application for common mode chokes is in motor control circuits. In motor control circuits, the choke is used to reduce the effects of electrical noise generated by the motor itself, as well as any other sources of electrical noise, such as radio frequency interference. The choke will help to reduce the chances of false triggering in the motor control circuit, preventing the motor from running unnecessarily, or even starting at the wrong time.

Another major application for common mode chokes is in the protection of data cables. High-frequency noise generated by the power supplies, as well as any other sources, can interfere with the signal strength of data cables, making them unreliable for data transmission. By installing a common mode choke within the data cable, the high-frequency noise is reduced, allowing for more reliable data transmission.

Common mode chokes are also used in high-speed switching applications to provide isolation for the high-frequency signals. The choke will create an inductive field which blocks any high-frequency signal, allowing signals to travel through the system without interference. This is particularly beneficial for applications such as Ethernet, USB, and other high-speed data transfer protocols.

Common mode chokes are a cheap and effective way to protect sensitive electronics from high-frequency noise and interference. Whether it’s used in motor control circuits, data cables, or high-speed switching applications, the DFSG-20-0002 is a great example of a common mode choke that can provide reliable noise filtering and signal stabilization.
