The B82422A1103K100V3 is a series of common mode chokes manufactured by EPCOS (TDK). These chokes are designed to suppress common mode noise in various electronic devices and systems. Common mode noise is a type of electromagnetic interference (EMI) that can disrupt the performance of sensitive circuits.

Applications:

• Switching power supplies
• Electronic ballasts
• Frequency converters
• Motor drives
• Data and signal lines

Features:

• High common mode attenuation
• Compact design
• High rated current
• Wide frequency range
• RoHS compliant

Benefits:

• Effective suppression of common mode noise, improving signal integrity and reducing EMI emissions.
• Enhanced reliability and performance of electronic devices.
• Compliance with electromagnetic compatibility (EMC) standards.
• Space-saving design for integration into compact electronic devices.

Additional Details:

Common mode chokes such as the B82422A1103K100V3 are constructed using two or more windings on a common core. The windings are arranged so that the magnetic fields generated by differential mode currents cancel each other out, while the magnetic fields generated by common mode currents add together. This allows the choke to effectively block common mode noise while allowing differential mode signals to pass through. The specific electrical characteristics such as inductance, rated current, and DC resistance, can be found in the product datasheet. The core material and winding configuration are chosen to optimize performance for specific frequency ranges and applications.
