Common Mode Chokes are invaluable electronic components in nearly every industry. From automotive to medical, consumer electronics to aerospace, these powerful electromagnetic components are used to control electrostatic noise, electromagnetic interference, and even reduce the risk of electrical shock or fire. DSF-18-0006 is an example of a common mode choke, offering extensive electromagnetic interference suppression and filtering capabilities.This article will discuss the application fields and working principle of DSF-18-00006.

Application Field

DSF-18-0006 is used in a wide variety of applications, including:

• Automotive and commercial vehicles, including trucks, cars, buses, and motorcycles.
• Medical devices and instruments, including pacemakers, infusion pumps, and MRI machines.
• Consumer electronics, including cellphones, tablets, wireless networking equipment, and home theater systems.
• Industrial and controls, including machine tools, servo motors, and electrical testing equipment.
• Aerospace, including avionics, aircraft systems, and propulsion systems.

In all of these applications, the DSF-18-0006 filters out both common-mode and differential-mode electromagnetic interference. It is designed to provide extended frequency coverage (up to 50MHz), attenuate signals across the full frequency range (from 5kHz to 30MHz), and reduce the level of EMI/RFI generated by electrical and electronic equipment.

Working Principle

The DSF-18-0006 is designed to filter out both common-mode and differential-mode electromagnetic interference. The common-mode interference is controlled by a conductive EMI shield encapsulated in the core. The common-mode noise is absorbed by the shield, thus limiting the amount of interference that can reach the rest of the circuitry. The differential-mode interference is filtered by a set of internal ferrite beads. These beads act as inductive filters, absorbing the differential-mode signal and preventing it from propagating further.

The beads are connected in series in such a way to create a low-impedance pathway, which allows for a more efficient bandwidth and higher frequency attenuation. They also act as an "inductive bump," or impedance mismatch, to stop the high-frequency signals from propagating further. This helps to control EMI/RFI while also providing additional filtering. The choke also provides extended frequency coverage (up to 50MHz) and offers a substantial reduction in EMI/RFI levels.

In addition, the DSF-18-0006 also offers excellent thermal stability, durability, and longevity. The choke is designed to be robust enough to handle the harshest environmental conditions, and it is capable of withstanding high temperatures and extended use. This makes it an ideal choice for a wide range of applications.

Conclusion

The DSF-18-0006 is a powerful and reliable common mode choke that is used in a variety of applications. It is designed to provide extended frequency coverage, high attenuation, and effective EMI/RFI reduction. It is also highly durable and thermally stable, making it an ideal choice for industrial and commercial applications where reliability and performance are paramount. With its excellent filtering capabilities and impressive performance, the DSF-18-0006 is an invaluable component for a range of industries.
