Common mode chokes, sometimes referred to as line filters or line reactors, are devices used to reduce interference in a variety of electrical systems. One such device is the DLW5ATH112MQ2L. In this article, we will discuss the application field and working principle of this device.

DLW5ATH112MQ2L is a common mode choke with low leakage inductance. It’s made up of three cores, two of which have air coils wound around them. The third core has a shield to provide a low frequency cutoff. The device is designed to suppress common mode noise in equipment and systems with DC/DC converters, switching power supplies and other electrical power supplies.

In terms of application, the DLW5ATH112MQ2L is used in various applications including power electronics, AC/DC converters, permanent magnet synchronous motor drives, high frequency AC motor controllers, AC-DC rectifiers, IGBT power supplies, plate machines, and industrial machinery.

The working principle of this device is quite simple. It relies on the magnetic field that is generated when current flows through the windings of the core. This magnetic field creates a barrier which prevents the passage of common mode noise and also prevents interference between the device’s various components. The device also acts as an inductor which helps to filter out any unwanted interference.

The DLW5ATH112MQ2L is also designed to provide a high level of suppression of differential mode and common mode noise. This is achieved by the use of air gap cores, which help to reduce noise in the higher frequency range. The device also includes an EMI filter which helps to reduce EMI emission levels.

In addition, the DLW5ATH112MQ2L is designed with an open circuit pickup, which allows it to detect and filter out harmful noise without the need for any external components. This helps to reduce the cost of installation and makes the device more cost-effective.

Overall, the DLW5ATH112MQ2L is an effective and reliable common mode choke that can be used to reduce interference and improve system performance in a variety of power electronic and AC/DC converter applications. Its ability to suppress common mode noise and provide high levels of suppression of differential mode and common mode noise help to ensure that the device works effectively in even the most difficult situations.
