The BX2564W is a common mode choke manufactured by Pulse. It is designed to suppress common mode noise in various electronic circuits and power lines. Its primary function is to attenuate unwanted noise signals that are common to multiple conductors, thereby improving signal integrity and reducing electromagnetic interference (EMI).

Applications

• Power supplies
• LED lighting
• Networking equipment (e.g., Ethernet)
• USB interfaces
• Data communication lines

Features

• High common mode impedance: Effectively attenuates common mode noise.
• Low differential mode impedance: Minimizes signal attenuation for desired signals.
• Compact size: Allows for use in space-constrained applications.
• High current capability: Can handle high current levels without saturation.
• RoHS compliant: Compliant with environmental regulations restricting hazardous substances.

Benefits

• Noise reduction: Reduces EMI and improves signal integrity.
• Improved system performance: Minimizes interference with other sensitive circuits.
• Compact design: Enables smaller and more compact product designs.
• Reliable performance: Provides consistent and reliable noise suppression.
• Environmentally friendly: Complies with environmental regulations.

Additional Details

The BX2564W is typically characterized by its inductance value, current rating, and DC resistance. The common mode impedance is frequency-dependent and should be selected based on the frequency range of the expected noise. The insertion loss, which is the attenuation of the desired signal, should be minimized. The choke is often used in conjunction with other EMI suppression components, such as capacitors, to create a comprehensive EMI filter. The datasheet provides detailed electrical characteristics, mechanical dimensions, and soldering recommendations. Proper placement and orientation of the choke on the PCB are important for optimal performance. The part is used in applications to meet specific EMC standards.
