Common Mode Chokes are widely used in electronic circuits as filters, usually to reduce common mode noise. The DLW21HN900SQ2L is one such product that provides extremely low common mode noise in a wide frequency range. Its application fields and working principles can be summarized as follows:

Application Field

DLW21HN900SQ2L Choke, is typically used in power harmonic filter circuits, primarily designed to reduce harmonic distortion of power supplies in AC/DC converter applications or any electronic circuits where high common mode noise should be eliminated. It is also applicable in other fields such as automotive electronics, instrumentation equipment, communication circuits, medical device connections, etc.

Working Principle

This Common Mode Choke operates by forming a magnetic field, through the core, that helps to suppress high frequency noise. This magnetic field creates an inductance that attenuates common mode voltages, preventing them from propagating throughout the circuit. At lower frequencies, the choke is less effective, while at higher frequencies, its performance is better. This is why it is important to choose the right DLW21HN900SQ2L choke for the application at hand.

Mounting and Installation

This Common Mode Choke is a two-hole, surface mount product, so it can be easily installed on any surface. It is designed to be mounted on a PC board or a flat surface. Its compact size and lead-free tin/plated finish make it compatible with automated production processes.

Electrical Characteristics

The DLW21HN900SQ2L Common Mode Choke offers good suppress performance in a wide frequency range. It offers a low common mode inductance of 1.5µH and a high isolation resistance of 8kohms, making it ideal for suppressing common mode EMF. It also offers a high saturation flux density of 75mT and an insulation resistance of at least 1000MΩ.

Conclusion

DLW21HN900SQ2L Choke is an ideal choice for suppressing common mode noise. It is a small and efficient product that can be easily installed on any surface. With its good suppress performance over a wide frequency range, it is suitable for a variety of applications where high common mode noise should be eliminated.
