Common Mode Chokes are one of the most important components in electronic systems. It is an electrical filter device designed to reduce the flow of common mode current and thereby reduce noise as well as interference in both on-board and off-board applications. Common Mode Chokes are used primarily for motor drive, audio amplifier, and power supply system applications.

Model DFKH-14-0003 is a Common Mode Choke designed for a variety of on-board and off-board applications. It is a four-terminal, high-performance Common Mode Choke with a wide frequency range of up to 125 MHz. It offers a reliable solution to the problem of EMI or RFI interference at high frequencies. The DFKH-14-0003 features a temperature range of -55°C to +105°C. It also offers high power dissipation with low thermal response.

The working principle of the DFKH-14-0003 Common Mode Choke is based on its design and construction. The device consists of two ferrite cores with Bobbin wire windings. A primary and a secondary winding are wound around the ferrite cores. The device is connected in series with the power line. The primary winding is connected between the line and neutral with the two ends of the secondary winding connected between the two ferrite cores. As a result, current flow in the primary winding is balanced out, or equalized, by a current flow in the secondary winding.

DFKH-14-0003 Common Mode Chokes are suitable for a variety of applications in the fields of motor drive, audio amplifier, power supply, and automotive electronics. In motor drive systems, the DFKH-14-0003 eliminates the noise generated due to leakage of the current from the motor, thus improving the drive performance. In automotive electronics, it can be used as a noise mitigator for audio amplifiers, thereby reducing the interference or noise caused by the high frequency current. Moreover, the DFKH-14-0003 can be used in the power supply system to provide enhanced power efficiency and reduced power supply noise when used with a switching power supply.

The DFKH-14-0003 Common Mode Choke is an efficient, effective, and reliable way to reduce the amount of electromagnetic interference and radio frequency interference. It offers high performance while operating in a wide temperature range. This makes it ideal for a variety of on-board and off-board applications. It is also extremely simple to install and configure, making it easy to integrate into existing systems.
