Common Mode Chokes

Common mode chokes, also known as common mode noise filters, are essential components to be used in various applications, such as in the industrial field and the telecommunication area. They are specifically designed to capture and dissipate electrostatic and electromagnetic interference, allowing current to flow through them in one direction, which can be used to cancel out a certain component of noise, thus decreasing its overall measurement. Working in the range of DC – very high frequency (VHF) and covering a broad range of power levels, common mode chokes are defined by their current rating, inductance, and frequency range.

DKIL-0331-1005 is a common mode choke specifically manufactured for use in DC applications. It is designed to filter common mode noise and improve signal integrity in high-frequency applications, including communication, transmission, energy, and others. The DKIL-0331-1005 is a single-channel device, with a channel rating of up to 10A. It has an inductance of 330uH and a Q of 60 at 100MHz.

The working principle of the DKIL-0331-1005 is based on the basic laws of physics, namely Faraday’s Law of Induction and Lenz’s Law. Faraday’s Law states that the magnitude of an induced e.m.f. in an inductor is directly proportional to the rate of change of the current passing through it. This means that when the current through an inductor is changing rapidly, an induced emf. is generated that opposes the change and creates a resistance. This induced emf. acts to slow the rate of the changing current, and this is known as inductive reactance. On the other hand, Lenz’s Law states that the direction of an induced current always opposes the direction of the change of the magnetic flux that created it.

In the DKIL-0331-1005, the main function is to limit the rate of change of the current passing through it and filter out common mode noise in DC applications. The DKIL-0331-1005 works by creating high impedance in one direction to block any common mode noise while allowing the desired signal pass through in the other direction. The high impedance created by the DKIL-0331-1005 limits the rate of current change, effectively isolating the noise from the desired signal. As a result, the interference is filtered out, allowing more of the desired signal to pass through with improved signal integrity.

Overall, the DKIL-0331-1005 is an ideal component for DC applications requiring effective common mode noise filtration. It is specifically designed for use under high frequencies and its high impedance enables a level of filtration that is not achievable by other components. Its working principle also ensures that only the desired signal is allowed to pass through, improving signal integrity and reducing interference.
