The PLP3216S551SL2T1 is a common mode choke coil manufactured by Murata Electronics North America. It's designed to suppress common mode noise in differential signal lines, commonly used in various electronic devices to improve signal integrity and reduce electromagnetic interference (EMI).

Applications:

• USB Lines: Suppression of common mode noise on USB data lines for improved data transmission.
• HDMI Lines: Filtering common mode noise in HDMI signals to maintain video quality.
• LVDS Interfaces: Common mode noise reduction on LVDS (Low Voltage Differential Signaling) lines.
• CAN Bus: Common mode noise filtering in CAN (Controller Area Network) bus systems.
• Ethernet: Used to reduce common mode noise on Ethernet cabling.
• Audio Lines: Common mode noise rejection for balanced audio signals.

Features:

• Common Mode Choke: Designed to attenuate common mode noise while allowing differential signals to pass through with minimal attenuation.
• Small Size: Compact size for space-constrained applications.
• High Impedance: Offers high common mode impedance for effective noise suppression.
• Low Differential Mode Impedance: Low differential mode impedance to minimize signal distortion.
• Surface Mount Device (SMD): Designed for surface mount assembly.
• RoHS Compliant: Complies with RoHS (Restriction of Hazardous Substances) directives.

Benefits:

• Improved Signal Integrity: Reduces common mode noise, leading to improved signal integrity.
• Reduced EMI: Attenuates EMI emissions, helping to meet regulatory compliance requirements.
• Enhanced System Reliability: Improved signal quality contributes to increased system reliability.
• Space Saving: Compact size allows for use in tight spaces.

Additional Details:

The PLP3216S551SL2T1 has an impedance of 550 Ohms at 100 MHz. The DC resistance is very low to prevent signal attenuation. It is available in a 1206 (3216 metric) package. It's used for noise suppression in high speed differential signal lines where space is a constraint.
