Common Mode Chokes are components that allow direct current (DC) to pass through them while blocking the flow of alternating current (AC). In order to effectively limit AC signal in a system, common mode chokes are often implemented. The DKFS-6248-02D5, manufactured by Xingsheng Technology Co. Ltd., is an example of a common mode choke.

The DKFS-6248-02D5 is a small, two-pin common mode choke, measuring 19.7mm by 11.2mm by 6.2mm. Its ID is 16mm, and it has inductances ranging from 100μH to 1000μH. This multipurpose choke consists of primary and secondary wire windings that are wound around a ferrite core with slight gaps between them. It is designed to reduce EMI/RFI generated by switching loads that cause common mode noise. DKFS-6248-02D5 offers superior filtering performance, with high attenuation in the range of 150kHz to 30MHz, attaining better than 70dB. With an operating temperature range of -40℃ to 85℃, this choke can meet the needs of different applications.

The DKFS-6248-02D5 can be used in various applications such as display interface, USB interface, LAN, and HDMI. This component is ideal for eliminating common mode noise from any system that operates at frequencies ranging from 150kHz to 30MHz. It can also be used as a bypass filter for Ethernet systems or Mains power lines. In addition to these applications, it can be utilized in LED drivers or power adapters.

The purpose of a common mode choke is to filter common mode interference in AC circuits. The common mode interference may be induced by EMI or ESD affecting power supplies, causing oscillations or disruption in the system or an increase in output noise. Generally, this type of interference is eliminated through the application of inductive components. The DKFS-6248-02D5 operates on the principle of inductance. It acts as a differential-mode voltage filter by using the inductance of the ferrite core to oppose the flow of different frequencies in both directions. This helps to reduce the magnitude of common mode interference, resulting in a clearer and purer signal.

The DKFS-6248-02D5 is a robust and reliable common mode choke designed for use in high signal-noise ratio systems, filtering out frequencies from 150 kHz to 30 MHz. With high attenuation and superior filtering performance, this component is ideal for eliminating common mode EMI/RFI and can be used in a variety of applications such as display interface, USB interface, LAN, HDMI, LED drivers, and power adapters.
