DLW31SN601SQ2L

Common Mode Chokes (CMCs) are electronic components widely used in communication and signal lines, including power lines, to achieve noise discrimination, enhance line impedance matching, and filter out spurious signals. Among them, the DLW31SN601SQ2L is a type of Wide Line Common Mode Choke that is used in various electronic applications due to its excellent performance.

DLW31SN601SQ2L provides excellent high frequency common-mode noise suppression and can effectively reduce the crosstalk between inputs and outputs. Common mode choke can be used in high speed differential line driving circuits, differential line receivers, driving multiple loads, power lines and digital devices. It is also suitable for ESD protection, high-frequency power circuit, switching power supply, common mode power filter, power line radiation reduction, and signal circuit suppression.

The working principle of DLW31SN601SQ2L is based on the fact that at high frequencies, there is a significant difference in impedance between the differential mode and the common mode. Therefore, if a common mode line is connected to a wide line common mode choke, the common mode current can be effectively absorbed by the choke, while at the same time, the impedance per unit length for the differential mode can be remain unaffected or decreased slightly (depending on the configuration).

The DLW31SN601SQ2L consists of a core, two windings, and two shield layers. The core is made of an alloy that has high saturation flux density and high permeability, which allows the choke to work at high frequency with low loss. The two windings can be arranged in a single layer or distributed in two layers according to user requirements. Each layer consists of two windings that are wound in opposite directions to improve noise cancellation. In addition, the two shield layers can provide additional protection against external electromagnetic interference.

DLW31SN601SQ2L provides excellent signal integrity and can handle large common-mode noise currents with very low losses at high frequencies. Furthermore, due to its small size and flat package design, DLW31SN601SQ2L is simple to install and does not require additional circuit board space. It also provides an excellent cost/performance balance, making it a great choice for various applications.

In summary, the DLW31SN601SQ2L wide line common mode choke is very useful in communication and signal lines, and can be used in various applications such as power line radiation reduction, switching power supply, signal circuit suppression, high-frequency power circuit and ESD protection. It provides excellent signal integrity and effectively suppresses common-mode noise within a wide frequency range.
