SCF25-08-1300 Filters

Common Mode Chokes, also known as EMC chokes, are widely used in data transmission, power line protection, signal filtering, and anti-interference devices. This type of choke is mainly used to eliminate common mode interference in the system, and is composed of two or more windings wound on the same magnetic core. SCF25-08-1300 is one type of common mode choke with smaller size, greater current carrying capacity, and a broader frequency range than traditional common mode chokes. This article will introduce its application field and working principle in detail.

Application Field

The application field of SCF25-08-1300 is in audio, video, telecommunication, high-end studios, serial communications, and digital communication systems, all of which require strict control over common mode EMI signals. It is suitable for the protection of high-speed data lines such as Gigabit Ethernet. The SCF25-08-1300 can filter out any unwanted high frequency interference, which helps to protect sensitive electronic devices from EMI radiation.

Working Principle

The working principle of SCF25-08-1300 is to suppress the electricity densities of the common-mode current, which need to remain constant in any condition. To achieve this, the SCF25-08-1300 consists of several inductive components in a series-parallel circuit configuration, which create a wideband multi-structure common-mode filter. This filter reduces unwanted harmonic currents by creating an attenuating reflection effect.When the common-mode signal reaches the input of the filter, it passes through the parasitic capacitances of its components and creates an attenuating reflection. This attenuating reflection introduces a voltage drop into the common-mode signal, resulting in a reduction of its voltage. By reducing the common-mode signal\'s voltage, the common-mode currents can be suppressed, thus allowing the wanted signals to pass through the filter.

Conclusion

The SCF25-08-1300 is an ideal common-mode choke when it comes to high-speed data communication cables and other applications that require tight common-mode EMI emissions. It can eliminate common-mode interference and protect sensitive electronic devices from EMI radiation. The SCF25-08-1300 is smaller, has greater current carrying capacity, and a broader frequency range than traditional common-mode chokes.
