The B82422A3220J100V3 is a common mode choke manufactured by EPCOS (TDK). It is specifically designed to attenuate common-mode noise in electronic circuits. Common-mode noise refers to unwanted electromagnetic interference (EMI) that appears simultaneously on multiple conductors with respect to a common reference point (ground).

Applications

• Switch-mode power supplies (SMPS)
• Frequency converters
• Power line filters
• Electronic ballasts for lighting
• Data and signal lines

Features

• Excellent common-mode noise suppression characteristics
• Compact design for space-constrained applications
• High rated current capability
• Compliant with RoHS standards

Benefits

• Reduces conducted EMI, improving the overall electromagnetic compatibility (EMC) performance of the system.
• Enhances the stability and reliability of electronic devices by minimizing noise interference.
• Aids in meeting regulatory requirements for EMC emissions.

Additional Details

Typical specifications for the B82422A3220J100V3 (always refer to the official datasheet for definitive values) include:

• Inductance: Approximately 22 μH (This is an estimated value; the datasheet will provide the exact inductance value and tolerance).
• Rated Current: The datasheet will specify the maximum continuous current the choke can handle at a given ambient temperature. This value is crucial for preventing overheating and ensuring reliable operation. Expect this to be in the range of several amps.
• Rated Voltage: 100 V (This value is explicitly given in the part number).
• Test Voltage: This represents the voltage that the component can withstand during testing without dielectric breakdown. It will be indicated in the datasheet.
• Operating Temperature Range: Typically from -40°C to +125°C, but confirm with the datasheet.

Common mode chokes operate by presenting a high impedance to common-mode currents while allowing differential-mode currents (the desired signal) to pass through with minimal attenuation. This is achieved through a specific winding configuration on a ferrite core. Always consult the official EPCOS (TDK) datasheet for detailed electrical characteristics, surge current ratings, and other critical parameters before incorporating this component into a circuit design.
