The PLW3216S222SQ2T1 is a common mode choke coil manufactured by Murata Electronics North America. It is designed to suppress common mode noise in differential signal lines, which are commonly found in high-speed data transmission applications. By attenuating common mode noise, this component helps to improve signal integrity and reduce electromagnetic interference (EMI).

Applications:

• USB 2.0/3.0 Data Lines: Used to filter common mode noise on USB data lines, ensuring reliable data transfer.
• HDMI Interfaces: Helps to maintain signal quality in HDMI connections by suppressing noise.
• LVDS (Low Voltage Differential Signaling) Interfaces: Reduces common mode noise in LVDS data transmission systems.
• Differential Audio Lines: Filters noise in balanced audio circuits, improving audio quality.
• CAN Bus Systems: Used in automotive and industrial applications to filter noise on CAN bus lines.
• Ethernet Cables: Attenuates common mode noise on Ethernet cabling for improved network performance.

Features:

• Common Mode Choke: Designed to specifically attenuate common mode noise.
• High Impedance: Offers high common mode impedance to effectively block noise.
• Low Differential Mode Impedance: Minimizes signal distortion by having a low differential mode impedance.
• Small Size: Compact size suitable for space-constrained applications.
• Surface Mount Device (SMD): Designed for surface mount assembly processes.
• RoHS Compliant: Complies with Restriction of Hazardous Substances (RoHS) directive.

Benefits:

• Improved Signal Integrity: Reduces common mode noise, resulting in cleaner and more reliable signals.
• Reduced EMI Emissions: Attenuates EMI, helping to meet regulatory requirements.
• Enhanced System Performance: Improved signal quality leads to better overall system performance.
• Space Saving: Compact size enables use in small form-factor devices.

Additional Details:

The PLW3216S222SQ2T1 has a common mode impedance of 2200 Ohms at 100 MHz. The DC resistance is kept low to minimize signal loss. It is available in a 1206 (3216 metric) package. The "SQ2" likely indicates the specific tolerance and performance characteristics, while "T1" may relate to packaging or tape and reel specifications.
