Common Mode Chokes

Common Mode Chokes, also known as line filters, are devices used to attenuate conducted and propagated noise on power or signal lines. A common mode choke consists of an oriented, inductive loop or winding, the primary purpose of which is to provide common mode noise isolation. Common mode Chokes are used in a variety of commercial and industrial applications, in equipment including telephones, audio systems, computers, and medical and scientific instruments.

The DLP2ADN201HL4L common mode choke is designed for high frequency applications covering a frequency range of up to 1 GHz. It is a compact package with an integrated C-Type ferrite core. It has excellent thermal performance and is terminated with both surface mount and through-hole pins to provide flexibility for different mounting options. The device is capable of providing up to 300mA of continuous current and 1200mA of instantaneous current.

The DLP2ADN201HL4L common mode choke has four differential line terminations, each of which is located on the output side of the device. The resulting power and signal line loop configuration gives it the desired common mode noise isolation. When connected with the appropriate wiring, the choke is capable of rejecting up to 40dB of common mode noise at 300MHz.

The DLP2ADN201HL4L\'s working principle is based on the principle of inductance, which is the tendency of an electric current to resist changes in the flow of electrical current in a conductor. The relationship between magnetic flux and inductance is referred to as Faraday’s Law, and it states that the inductance of a coil is proportional to the magnetic flux which links it. This property of a coil allows the DLP2ADN201HL4L common mode choke to attenuate common mode noise by increasing its impedance across its differential line terminations.

The DLP2ADN201HL4L can be used in a variety of applications, such as power line communications, telecommunications, automotive, industrial, and medical systems. Its differential line terminations and high-frequency properties offer a versatile solution for attenuating conducted and propagated noise in both low and high-power systems.

In conclusion, the DLP2ADN201HL4L is an ideal solution for common mode noise attenuation in a variety of applications and systems. Its C-Type ferrite core and differential line terminations allow it to reject significant amounts of noise up to 1GHz, making it well suited for power and signal line applications where lower noise levels are desired.
