The TG-4OP-0249-24 is a surface mount common mode choke from Sumida America Components Inc. These chokes are designed to suppress common mode noise in various electronic circuits. Common mode chokes are passive electronic components used to attenuate common-mode currents while allowing differential-mode currents to pass through unaffected. This makes them ideal for reducing electromagnetic interference (EMI) and improving signal integrity.

Applications:

• Power Line Filtering: Used to filter noise on AC and DC power lines.
• Signal Line Filtering: Employed in data and signal lines to reduce interference.
• USB Ports: Protects USB ports from common mode noise.
• Networking Equipment: Found in Ethernet and other networking interfaces to minimize EMI.
• Audio Equipment: Improves audio quality by reducing noise in audio circuits.

Features:

• Surface Mount Design: Allows for easy and efficient PCB assembly.
• High Common Mode Attenuation: Provides excellent suppression of common mode noise.
• Compact Size: Saves valuable board space.
• Wide Frequency Range: Effective across a broad range of frequencies.
• High Reliability: Ensures consistent performance in demanding applications.

Benefits:

• Reduced EMI: Minimizes electromagnetic interference, improving overall system performance.
• Improved Signal Integrity: Ensures cleaner and more reliable signal transmission.
• Enhanced Audio Quality: Reduces noise in audio circuits, resulting in clearer sound.
• Increased System Reliability: Protects sensitive components from noise-related damage.
• Compliance with Regulatory Standards: Helps meet EMI compliance requirements for various electronic devices.

Technical Specifications:

While specific technical specifications such as inductance, impedance, and current rating require a datasheet lookup for the TG-4OP-0249-24, common mode chokes generally have parameters like inductance (measured in Henries), impedance (measured in Ohms), rated current (measured in Amperes), and DC resistance (DCR). They are also characterized by their attenuation performance across a specified frequency range. The physical dimensions and operating temperature range are also key specifications to consider for integration into specific applications. The core material used in the choke (e.g., ferrite) influences its performance characteristics.
