The B82422A1104K100V3 is a common mode choke from EPCOS (TDK). Common mode chokes are designed to suppress common mode noise in electronic circuits. Common mode noise is unwanted electrical interference that appears simultaneously on multiple conductors with respect to ground.

Applications

• Switching power supplies
• Frequency converters
• Ballasts for lamps
• Consumer electronics
• Data and signal lines

Features

• High common mode noise suppression
• Compact size
• High rated current
• RoHS compliant

Benefits

• Reduces electromagnetic interference (EMI) in electronic devices.
• Improves the reliability and performance of electronic equipment.
• Helps meet regulatory requirements for EMC (Electromagnetic Compatibility).

Additional Details

The B82422A1104K100V3 choke exhibits the following characteristics (typical values, refer to datasheet for precise specifications):

• Inductance: 1 mH (This is a common value; the datasheet will confirm the exact inductance.)
• Rated Current: Likely in the range of 1-3 Amperes (Datasheet provides precise value, depending on temperature rise requirements).
• Rated Voltage: 100V (As indicated in the part number).
• Dielectric Strength: Specified in the datasheet; it indicates the voltage the choke can withstand without breakdown.
• Operating Temperature Range: Typically -40°C to +125°C (Datasheet confirms the exact range).

Common mode chokes work by creating a high impedance to common mode currents while allowing differential mode currents (the desired signal) to pass through with minimal impedance. The winding configuration is designed to cancel out the magnetic fields created by differential mode currents, preventing saturation of the core. It's essential to consult the official EPCOS (TDK) datasheet for detailed specifications, including impedance vs. frequency characteristics, rated current derating curves, and safety certifications before using this component in a specific application.
