The TCE1608-900-4P-T000 is a common mode choke manufactured by TDK Corporation. This choke is engineered to suppress common mode noise in a variety of electronic applications. Common mode chokes are passive components designed to attenuate common-mode currents while allowing differential-mode currents to pass unimpeded. This particular model belongs to TDK's TCE series of common mode filters, known for their compact size and performance.

Applications:

• USB Lines: Used in USB ports and cables to reduce common mode noise and improve signal integrity.
• HDMI Lines: Integrated into HDMI devices to filter out noise that can degrade video and audio quality.
• LVDS Interfaces: Employed in LVDS (Low-Voltage Differential Signaling) systems to minimize noise and ensure reliable data transmission.
• Power Lines: Implemented in power supply circuits to suppress noise and prevent interference with other components.
• Automotive Electronics: Utilized in automotive systems to protect against electromagnetic interference and ensure proper operation of electronic control units (ECUs).

Features:

• Compact Size: The 1608 (1.6mm x 0.8mm) footprint makes it suitable for space-constrained applications.
• High Common Mode Impedance: Offers effective attenuation of common mode noise.
• Low Differential Mode Impedance: Minimizes signal distortion and ensures signal integrity.
• Excellent Temperature Stability: Maintains consistent performance over a wide temperature range.
• RoHS Compliant: Meets environmental regulations regarding hazardous substances.

Benefits:

• Improved Signal Integrity: Reduces common mode noise, leading to clearer and more reliable signals.
• Reduced Electromagnetic Interference (EMI): Minimizes emissions and susceptibility to external noise, improving overall system EMC performance.
• Enhanced System Reliability: Protects sensitive components from noise-related failures, increasing system lifespan.
• Simplified Circuit Design: Provides a convenient and effective solution for common mode noise filtering.
• Compliance with Regulatory Standards: Helps in achieving compliance with EMI/EMC standards.

Additional Details:

This common mode choke has a specific impedance value at a defined frequency, and a rated current. These specifications are critical for selecting the appropriate choke for a given application. It has a four-line configuration which enables to filter two differential lines at once. The TCE series is designed for surface mount technology (SMT) which simplifies assembly.
