The LDC54899M03B-213 is a common mode choke from Murata Electronics. It is designed to suppress common mode noise in differential signal lines. This helps prevent electromagnetic interference (EMI) from affecting sensitive circuits and also prevents the circuit from radiating EMI. These chokes are commonly used in high-speed data communication lines.

Applications

• USB interfaces: Suppression of common mode noise in USB data lines.
• HDMI interfaces: Filtering noise in HDMI connections between devices.
• Ethernet lines: Noise filtering in Ethernet networks to ensure data integrity.
• DisplayPort connections: Used in DisplayPort interfaces to reduce EMI.
• LVDS interfaces: Noise suppression in LVDS high-speed data transmission.

Features

• Common mode noise suppression: Effectively attenuates common mode noise.
• High impedance at high frequencies: Provides high impedance to common mode currents.
• Low insertion loss: Minimizes signal attenuation in the desired frequency band.
• Compact size: Small form factor for space-constrained applications.
• Surface mount technology (SMT): Suitable for automated assembly.

Benefits

• Reduced EMI: Prevents electromagnetic interference from affecting sensitive circuits.
• Improved signal integrity: Ensures clean and reliable signal transmission.
• Compliance with EMC standards: Helps products meet electromagnetic compatibility requirements.
• Simplified design: Easy to integrate into existing circuits.
• Reliable performance: Provides consistent and stable noise suppression.

Additional Details

The LDC54899M03B-213 is typically specified with an impedance value at a particular frequency (e.g., 90 ohms at 100 MHz). It has a very low DC resistance to minimize signal loss. It’s manufactured using ferrite materials. It operates over a wide temperature range. The specific dimensions, impedance characteristics over frequency, and other electrical specifications are found in the product datasheet.
