The PE-64956, manufactured by Pulse A Technitrol Company, is a common mode choke. This choke is designed to suppress common mode noise in a variety of electronic circuits. Common mode chokes are crucial for reducing electromagnetic interference (EMI) and improving signal integrity in sensitive applications. They are often used in power lines, data lines, and communication cables.

Applications

• Power Line Filtering: Used to reduce common mode noise on AC or DC power lines.
• Data Line Filtering: Employed on data communication lines (e.g., USB, Ethernet) to suppress noise and prevent data corruption.
• Signal Line Filtering: Utilized in audio and video signal lines to improve signal quality and reduce interference.
• Switching Power Supplies: Integrated into switching power supplies to minimize EMI and ensure compliance with regulatory standards.
• Motor Drives: Found in motor drive circuits to suppress noise generated by the motor and inverter.

Features

• Common Mode Attenuation: Provides significant attenuation of common mode noise signals.
• Low Differential Mode Insertion Loss: Minimizes signal degradation for differential signals.
• Compact Size: Small footprint allows for easy integration into space-constrained designs.
• High Impedance: Offers high impedance to common mode currents, effectively blocking noise.
• Wide Frequency Range: Designed to suppress noise over a broad frequency spectrum.

Benefits

• Reduced EMI: Effectively suppresses electromagnetic interference, improving system performance.
• Improved Signal Integrity: Minimizes noise and distortion in signal lines, enhancing signal quality.
• Enhanced System Reliability: Protects sensitive circuits from noise-induced failures.
• Compliance with Regulatory Standards: Helps systems meet EMI/EMC requirements for regulatory compliance.
• Easy Integration: Compact size and standard mounting options simplify integration into various circuit designs.

The PE-64956 typically comes in a through-hole or surface-mount package. Its specific inductance, impedance, and current ratings are detailed in the manufacturer's datasheet. Proper selection of a common mode choke requires careful consideration of the frequency range of the noise and the current requirements of the application. Shielding may also be employed to reduce radiated emissions.
