The PCE933-4581001 is a common mode choke designed and manufactured by Toko America Inc. Common mode chokes, also known as common mode inductors or filters, are electronic components used to suppress common-mode noise in electronic circuits. This particular choke is likely used in applications where electromagnetic interference (EMI) needs to be minimized, such as in power supplies, data lines, and audio/video equipment.

Applications

• Power supplies to reduce conducted EMI.
• USB and data lines to filter common mode noise and prevent data corruption.
• Audio and video equipment to improve signal quality by reducing noise.
• Network interfaces (e.g., Ethernet) to suppress noise on the data lines.
• General electronic devices requiring EMI suppression.

Features

• High Common Mode Impedance: Provides significant attenuation of common mode noise.
• Low Differential Mode Impedance: Minimizes signal distortion for differential signals.
• Compact Size: Enables use in space-constrained applications.
• High Current Capacity: Suitable for applications with relatively high current levels.
• RoHS Compliant: Meets environmental regulations regarding hazardous substances.

Benefits

• Reduced EMI: Effectively suppresses common mode noise, improving the overall electromagnetic compatibility of the device.
• Improved Signal Integrity: Filters out noise, leading to cleaner and more reliable signals.
• Enhanced System Performance: Minimizing noise and interference can improve the performance and stability of the system.
• Compliance with Regulations: Helps meet regulatory requirements for EMI emissions.
• Increased Reliability: Protecting circuits from noise spikes and interference can increase the lifespan of electronic components.
