Common Mode Chokes are designed to filter the unwanted electromagnetic interference (EMI) by blocking the undesired high frequency noise to prevent it from entering the sensitive circuits. The DFKH-22-0005 model is a excellent example, which is widely used in a broad range of applications such as automotive, automotive electronics, consumer electronics, switched-mode power supplies, power inverters, solar inverters, industrial automation, laboratory and test instrumentation, Data center, home appliances, and some far-field communications.

The working principle of the DFKH-22-0005 common mode choke is very simple and efficient. It contains multiple turns of insulated wire with a core surrounded by a shielding sleeve. The insulated wire act as an inductor and it is connected to the power supply source. This magnetic field created by the coil acts as a filter, blocking all the electromagnetic waves that would otherwise enter the system. The design is also resistant to saturation, meaning high energy that could burst through the magnetic field is efficiently absorbed. The filtered noise is further reduced due to a variety of physical and electrical characteristics.

The DFKH-22-0005 is offered in an Axial Leaded version with height of 7.6mm and dia 20mm. It is capable of operating in environments up to 125°C and capable of handling currents up to 4Amp. It is fully RoHS compliant and recognized by the UL 94V-0 flame retardant label.

DFKH-22-0005 is designed to be used in Circuits containing I/O data buses, such as CANbus, LINbus, Ethernet, HDMI, Power over Ethernet (PoE) or USB. Additionally, it is widely used in all types of switching power supplies, high-speed signals and data transmission, consumer electronics, automotive window and stereo systems and other applications involving high-frequency noise attenuation.

In summary, the DFKH-22-0005 has a wide range of applications and working principle. It is used in automotive, automotive electronics, consumer electronics, switched-mode power supplies, power inverters, solar inverters, industrial automation, laboratory and test instrumentation, Data center, home appliances, and far-field communications. Its built-in filter effectively provides good protection from undesirable high frequency noise. It is able to operate under extremely high temperature and moderate currents. Thus, the DFKH-22-0005 common mode choke is a great solution for all sorts of EMI noise reduction in different scenarios.
