Common Mode Chokes, or CMC, addresses one of the most common electrical issues — electromagnetic interference (EMI). CMC operates by reducing the amount of stray electrical energy caused by currents or voltages being induced from one circuit to another. The DLW5ATH151MQ2L series from Infineon is one of the most versatile solutions available in the market, with a wide range of applications and working principles.

The DLW5ATH151MQ2L is designed to reduce unwanted high frequency interference between two electrical locations or before it reached to the ground. It does this by diverting current from one circuit onto another with a very high impedance level. By doing so, it prevents interference from settling in any one circuit and then filtering out any remaining interference.

To achieve this, the DLW5ATH151MQ2L uses two forms of induction: line-to-line and line-to-ground. Line-to-line CMC is used to reduce the common mode noise by using two sets of windings placed in diametrically opposite directions that works as an inductor, allowing current to flow in one direction while rejecting current from the other. Whereas line-to-ground CMC uses only one winding placed over the core to tame both common and differential mode noise. The DLW5ATH151MQ2L series is designed for low impedance connection and low penetration of high frequency current.

In addition to CMC, the DLW5ATH151MQ2L series contains two ferrite cores for EMI suppression. These cores – which are made of a highly permeable material – act as inductors, providing isolation from interfering signals. They also reduce high frequencies by creating a low impedance path. This process is known as impedance matching.

The DLW5ATH151MQ2L series is designed to reduce electrical noise and is used to help ensure reliable communication systems. It can be used in both commercial and military applications, including broadcast and wireless communication sets, medical equipment, data processing and processing systems, power electronics, automotive electronics, and industrial control systems. The high efficiency and robust design of the DLW5ATH151MQ2L makes it an ideal solution for these applications.

The DLW5ATH151MQ2L series is available in various sizes, ranging from 2 to 10 µH to fit into a variety of different application spaces. The series offers an all-in-one solution for CMC as well as EMI suppression, making it an attractive option for many design engineers. It also features high insertion loss and low bucking, meaning that it can effectively eliminate a wide range of EMI problems.

In summary, the DLW5ATH151MQ2L series is a versatile solution that can address a wide range of EMI problems, from line-to-line interference to line-to-ground noise. It is ideal for applications in broadcast and wireless systems, medical electronics, power electronics, and industrial systems, and its two ferrite cores offer exceptional shielding and impedance matching capabilities. The DLW5ATH151MQ2L series is easy to incorporate into existing designs and provides the foundation for an effective and reliable EMI solution.
