Common mode chokes, colloquially referred to as noise filters, are integrated circuits designed to segregate EMI (electromagnetic interference) from interfering within sensitive data lines, preventing or minimizing unwanted noise from entering and causing disruption. In particular, common mode chokes are used in pairs to isolate the path through which unwanted voltage and current is carried. A common mode choke with a part number of DLW31SN900SQ2L is widely utilized in application fields including domestic and industrial automation equipment, automotive power systems, and consumer electronics, among others.

The basic working principle of the DLW31SN900SQ2L common mode choke involves the combination of two inductors in antiparallel configuration. This bipolar arrangement, with an inductor in each direction, creates a solution capable of suppressing common mode interference over a wide frequency range and wide range of currents. The inductors are also magnetically coupled, allowing the wound coil to provide enough impedance to stop the current from passing through it and blocking any EMI. The DLW31SN900SQ2L common mode choke is also equipped with a wide range of damping and filtering components that further increase the attenuation, providing total protection from EMI.

Moreover, a maximum current rating for the DLW31SN900SQ2L common mode choke of 3 amperes is also available. This current rating allows it to handle very high current levels and still guarantee a high quality noise-free environment. Furthermore, a low leakage current and tight inductance tolerance around its nominal value of 500mA +/-20% ensure a reliable operation and very low noise generation. The low ohm resistance (0.128) of this common mode choke also reduces the power demands of the application, making for an optimum noise attenuation performance.

Overall, the DLW31SN900SQ2L common mode choke is an extremely versatile integrated circuit capable of providing superior performance for a wide variety of applications. With its ability to handle high current levels, tight inductance tolerance, and low resistance, the DLW31SN900SQ2L common mode choke is an ideal choice for applications that require a reliable and effective noise attenuation solution.
