The ULC0504D is a Common Mode Filter manufactured by Shanghai Leiditech Electronic Technology Co., Ltd. It is designed to suppress common-mode noise while allowing differential signals to pass through with minimal attenuation. This component is commonly used to improve signal integrity and reduce electromagnetic interference (EMI) in high-speed data transmission lines.

Applications:

• USB 2.0/3.0 data lines
• HDMI interfaces
• Ethernet ports
• DisplayPort interfaces
• LVDS interfaces

Features:

• High common-mode attenuation
• Low differential-mode insertion loss
• Small footprint package
• High ESD protection
• RoHS compliant

Benefits:

• Improved signal integrity by suppressing common-mode noise, resulting in cleaner and more reliable data transmission.
• Minimal signal degradation due to low differential-mode insertion loss, ensuring accurate data transfer.
• Space-saving design with a small footprint package, making it suitable for compact electronic devices.
• Enhanced system protection against electrostatic discharge (ESD), preventing damage to sensitive electronic components.
• Environmentally responsible choice due to RoHS compliance.

Additional Details:

The ULC0504D typically features a common-mode attenuation of -20dB or better over a wide frequency range. It is commonly available in a small DFN or similar surface-mount package. The filter is designed to match the impedance of high-speed data lines, ensuring minimal signal reflections.

Detailed specifications usually include parameters like common-mode impedance, differential-mode impedance, insertion loss, return loss, and ESD withstand voltage. Designers should refer to the manufacturer's datasheet for precise values and recommended operating conditions to ensure optimal performance and reliability.

This common-mode filter is designed for easy integration into a wide range of electronic devices, offering a robust and cost-effective solution for EMI suppression and signal integrity improvement. Its high performance and compact size make it a popular choice among design engineers.
