Common Mode Chokes are devices that reduce the amount of will conduction or interference in circuits. They employ inductors to stop high frequency noise from entering other parts of the circuit. They are sometimes called Line Filtering Chokes. Common mode chokes are found in a variety of applications including switching power supplies, motor drives, communication equipment, and consumer electronics that require power line filtration.

The NFP0QSN122HL2D is a common mode choke designed for AC/DC Power Lines and Bus Common Mode Choke applications. It is a low profile, axial leaded device with a wide operating temperature range of – 40°C to + 125°C. The device has a frequency response range from 1 MHz to 250 MHz, and a rated current up to 1.5A. The key features of the NFP0QSN122HL2D are its Fast Turn-on Time, Low Profile, Wide Temperature Range, and High Current Rating.

The working principle of the NFP0QSN122HL2D common mode choke is based on Faraday’s law of induction. It works by creating a magnetic field around the choke which induces eddy currents in conducting material, preventing the flow of will conduction and interference between the input and output sides of the circuit. This works by the two coils in the choke generating opposing electromagnetic fields, which are then used to oppose any will conduction or interference in the circuit.

The wide applications of the NFP0QSN122HL2D common mode choke include: Automotive networks, Motion Control Inverters, Switch Mode Power Supplies, and Lighting Equipment. In automotive networks, the common mode choke helps reduce the level of noise that is allowed to enter the control system, and it also helps provide input surge protection when the electronic accelerator is engaged. In motion control inverters, the common mode choke can help reduce interference in the motor drive signals. This helps the motion control inverter to operate more efficiently and accurately. In switch mode power supplies, the common mode choke is used to reduce the amount of AC ripple voltage that is allowed to enter the power supply, providing improved power efficiency and stability. Finally, the common mode choke is also used in lighting equipment, helping to provide an efficient, clean power supply for the light source.

In conclusion, the NFP0QSN122HL2D common mode choke provides reliable noise reduction and interference suppression for a variety of applications. Its low profile, fast turn-on time, wide temperature range, and high current rating make it an ideal choice for many applications. The common mode choke works on the basis of Faraday’s law of induction, using two coils to generate opposing electromagnetic fields which are then used to oppose any will conduction or interference in the circuit. The wide range of applications for the common mode choke includes automotive networks, motion control inverters, switch mode power supplies, and lighting equipment.
