DLW21SN900HQ2L Typical application Circuitry

DLW21SN900HQ2L

The DLW21SN900HQ2L is a common mode choke, an electronic component used primarily for suppressing common mode electromagnetic interference (EMI) in various electronic circuits. These chokes are critical in applications where high-frequency noise can disrupt the functionality of electronic devices.

Application Scenarios

The DLW21SN900HQ2L is typically used in:

- USB interfaces for noise suppression.

- Ethernet cables to reduce EMI.

- Signal lines in mobile devices to enhance signal quality.

- Digital communication ports in consumer electronics.

Parameter Features

Key characteristics of the DLW21SN900HQ2L include:

- High common mode impedance at relevant frequencies.

- Compact surface-mount design suitable for high-density circuit boards.

- Low differential mode impedance to maintain signal integrity.

- Suppresses common mode noise in high-speed data lines effectively; intended for use in digital data transmission applications at high speeds.

EMI reduction using an Ethernet cable for circuit connection

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 the Ethernet lines.

- Connection Method: Route the TX+ and TX- (transmit) and RX+ and RX- (receive) lines of the Ethernet cable through the DLW21SN900HQ2L. 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 DLW21SN900HQ2L onto the PCB, adhering to 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 DLW21SN900HQ2L at an appropriate distance from the Ethernet port to effectively suppress noise while maintaining signal integrity.

Heat Dissipation

- Location: General placement within the circuit.

- Purpose: To maintain the performance and durability of the choke.

- Connection Method: Ensure that the DLW21SN900HQ2L is placed in an area of the PCB with minimal exposure to heat from other components.

Design-Related Issues

When creating circuits with the DLW21SN900HQ2L, take into account:

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

- Physical Size and Layout: Account for the component's size and positioning 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: Ensure that the placement of the choke does not degrade the Ethernet data signals.

In conclusion, the DLW21SN900HQ2L is essential in applications like Ethernet cable EMI reduction, where its ability to suppress common mode noise while preserving signal integrity is crucial. Proper integration, considering impedance, physical layout, thermal aspects, and signal quality, is key to its successful use in electronic systems.
