Common Mode Chokes are electrical devices used to prevent electromagnetic interference (EMI) in equipment and circuits. They are primarily used in applications where the characteristics of a metal oxide varistor (MOV) are inappropriate or undesirable, such as when more stringent requirements are needed for EMI attenuation, high-frequency operation, or temperature range. Common Mode Chokes are also used in Advanced Telecom Computing Architecture (ATCA) applications, where the use of circuit boards with densely packed components requires low-radiation EMI/RFI filtering solutions.

DKLP-0329-0330 is one of the widely used common mode chokes in the market. It is a ferrite based common mode filter that provides a high impedance to common mode noise lines, while having very low insertion loss for signal lines. The housing is made of aluminum with an integrated temperature and EMI shielding that offers excellent performance in all environments. The DKLP-0329-0330 is RoHS compliant and can operate over a wide temperature range from -40°C to 105°C.

The field of application for DKLP-0329-0330 common mode chokes range from consumer electronics, automotive, aerospace and defense, to industrial applications requiring EMI filtering. It is used for power line filtering, power supply filtering, tuned circuits, high-speed signal lines, and differential signal lines. It is also well suited for applications where tighter specifications need to be met, such as in higher frequency applications. DKLP-0329-0330 can also be integrated into a Printed Circuit Board (PCB) for easy installation.

DKLP-0329-0330’s working principle is based on the Faraday effect. This effect is caused by a change in the magnetic flux linked to a circuit, wherein the flux generates a voltage across the circuit. The flux is created by the movement of electric current. The DKLP-0329-0330 is designed to provide an inductive impedance to common mode noise by providing a magnetic field that opposes the movement of the flux. This creates an opposition to the change in flux, which helps to reduce the amount of noise that is transmitted to sensitive electronic components.

To optimize the performance of VDKL-0329-0330, it is important to consider the current carrying capacity of the choke. The maximum current rating will depend on the size and frequency of the amperes utilized. It is also important to keep in mind that it is possible that the current rating may be exceeded, since the resistance of the choke against the current is dependent on the size of the used ferrite core and the number of windings. To provide an optimum balance between the current rating and the EMI/RFI filtering capability, it is important to use DKLP-0329-0330 in combination with other components such as capacitors and resistors. When used correctly, the DKLP-0329-0330 common mode choke can provide an efficient and reliable method for attenuating EMI/RFI interference.
