Common Mode Chokes: CM7560-825 Application Field and Working Principle

Common mode chokes, also known as common mode inductors, are devices used to reduce common mode interference for electronic equipment. Common mode chokes are widely used in a variety of fields because of the effective suppression of common mode interference, such as Telecommunications, Power supplies, Medical equipment, and Computers. Specifically, the CM7560-825 common mode choke range is widely used for the internal power management of various electronic applications across a number of industries.

The CM7560-825 range presents high power common mode suppression through an extended frequency range, with a rated current up to 8A and an impedance range up to 200μH. The product range provides the ability to operate within a temperature range of -40°C to +125°C, and offers a tight choke size (10.2x7.6mm). The material for the CM7560-825 range is alumina ceramic, with Au plated copper pins.

The working principle of a common mode choke is based on a traditional analogy of a traditional inductor, but instead of having a single winding it has two. The CM7560-825 range provides three windings, allowing for a higher degree of shielding. The three windings form a magnetic loop, surrounding the signal line and work together to reduce the common mode noise emission generated by the source.

The CM7560-825’s magnetic fields interact with one another, creating a topology that filters out common mode noise present in the signal. These inductors have a twofold purpose: providing high impedance at the frequency of the common mode noise and providing low impedance to the signals passing through the line. In this way, the CM7560-825 range limits the amount of common-mode noise present in the signal while allowing signal to pass through.

The CM7560-825 range has been designed for a wide range of applications, providing a solution for different levels of common mode suppression. This high-performance range provides the flexibility needed for many applications, with the added benefit of being small, robust, and easy to install. No external shielding is required, which leads to improved system performance and reduced costs.

The CM7560-825 range has a number of features to maximize its performance. These include high current capacity, low ESR, and uniform inductance. The high current capacity allows for improved system performance and reliability, while the low ESR ensures efficient operation and excellent noise suppression. The uniform inductance guarantees consistent performance, ensuring that each inductor in the range will behave in the same way.

In summary, the CM7560-825 range is a high-performance range of common mode chokes, used in a variety of applications to reduce common mode interference. The range provides the flexibility necessary for a variety of applications, with the added benefits of being small, robust, and easy to install. The range also demonstrates excellent performance due to its high current capacity, low ESR, and uniform inductance.
