Common mode chokes are electrical components, also known as differential mode chokes, which are mainly used to suppress high frequency interference or EMI (electromagnetic interference) noise in certain circuits or systems. They are made up of two or more windings wrapped around a core, with the windings connected so that the current flows in opposite directions and creates a magnetic field that opposes an external magnetic field. The DLW5ATH231TQ2K is just one model of Common Mode Choke, and its application field and working principle are discussed in this article.

The DLW5ATH231TQ2K is primarily used as a power line filter in electronic systems, and it is particularly designed to suppress high frequency EMI generated by switching-mode power supplies (SMPS). It is designed to be used with a 50 HZ, 1-phase voltage up to 220V, with a rated current of 8 Amps and a maximum operating temperature of up to 105°C. The DLW5ATH231TQ2K is also UL recognized, indicating that it adheres to all safety requirements and can be safely used in a variety of applications.

When it comes to the working principle of the DLW5ATH231TQ2K, common mode chokes are basically designed to provide differential mode currents with length of loop, with an impedance ratio of around 1:50. This means that the current through the choke will be relatively high compared to the current flowing through the circuit, resulting in a more uniform current distribution. The differential mode current is then filtered out, leaving only the common mode current and thus, reducing the amount of EMI present. The DLW5ATH231TQ2K is also designed to reduce the voltage harmonics, which can be caused by the switching-mode power supplies.

In addition, the DLW5ATH231TQ2K can also be used in audio/video distribution, as it has a very low resistance, allowing it to provide the same current through both windings. This makes it ideal for applications where the signal needs to be kept free from any kind of noise or interference. The high frequency EMI noise that would normally interfere with the signal is then effectively filtered out, allowing for better video and audio quality.

In conclusion, the DLW5ATH231TQ2K is a type of Common Mode Choke. Its primary application field is that of a power line filter in electronic systems, with the primary purpose of attenuating high frequency EMI generated by switching-mode power supplies (SMPS). It is also able to reduce the voltage harmonics present in the circuits. On top of this, it can also be used in audio/video distribution, where it can provide low resistance, which keeps the signal free from interference. All these factors make the DLW5ATH231TQ2K an ideal choice for many circuit designs and applications.
