DLW21HN900SQ2L Typical application Circuitry

DLW21HN900SQ2L

The DLW21HN900SQ2L is a common mode choke, specifically designed for filtering applications in electronic circuits. It is used to suppress common mode electromagnetic interference (EMI) in a variety of high-speed data and signal lines, making it an essential component for maintaining signal integrity and reducing noise.

Application Scenarios

The DLW21HN900SQ2L is typically used in:

- USB interfaces for noise suppression.

- Ethernet cable applications for EMI reduction.

- Devices for communication to enhance signal quality.

- Consumer electronics with high-speed data links.

Parameter Features

Key features of the DLW21HN900SQ2L include:

- High common mode impedance at relevant frequencies.

- Low differential mode impedance to maintain signal integrity.

- Compact surface-mount form factor.

- Designed for high-density PCB applications.

- Effective in suppressing common mode noise in high-speed data lines.

Circuit Connection - Ethernet Cable EMI Reduction

An example application in an Ethernet cable for EMI reduction:

Placement in Ethernet Line

- Location: Next to a device's Ethernet port.

- Purpose: To suppress common mode noise in Ethernet lines.

- Connection Method: Route the TX+ and TX- (transmit) and RX+ and RX- (receive) lines of the Ethernet cable through the DLW21HN900SQ2L. Each pair should pass through the choke's internal filter circuit.

Orientation and Mounting

- Location: On the printed circuit board (PCB) near the Ethernet port.

- Goal: To increase noise suppression's efficacy. - Connection Method: Solder the DLW21HN900SQ2L onto the PCB, following the recommended orientation and footprint for optimal EMI suppression.

Signal Integrity Consideration

- Location: Relative to the Ethernet lines.

- Purpose: To ensure the choke does not negatively affect the Ethernet signal quality.

- Connection Method: Position the DLW21HN900SQ2L at an appropriate distance from the Ethernet port to suppress noise effectively while maintaining signal integrity.

Heat Dissipation

- Location: General placement within the circuit.

- Purpose: To maintain choke performance and durability.

- Connection Method: Ensure that the DLW21HN900SQ2L is placed in an area of the PCB with minimal exposure to heat from other components.

Design-Related Issues

When creating circuits with the DLW21HN900SQ2L, take into account:

- Impedance Matching: The choke's impedance should be compatible with the Ethernet line to suppress noise effectively.

- Physical Size and Layout: Account for the component's size and position on the PCB for efficient assembly and optimal performance.

- Thermal Management: Consider the thermal environment to ensure the choke operates within its temperature range.

- Signal Integrity: Verify that the Ethernet data signals are not weakened by the choke's positioning.

In conclusion, the DLW21HN900SQ2L is crucial in applications like Ethernet cable EMI reduction, where its ability to suppress common mode noise while preserving signal integrity is essential. Proper integration, taking into account impedance, physical layout, thermal considerations, and signal quality, is key to its successful use in electronic systems.
