DLW21SN371SQ2L Typical application Circuitry

DLW21SN371SQ2L

The DLW21SN371SQ2L is a common mode choke, a specific type of filter used in electronic circuits for suppressing common mode electromagnetic interference (EMI).

Application Scenarios

The DLW21SN371SQ2L is commonly utilized in:

- USB interfaces for noise suppression.

- Ethernet cables for reducing EMI.

- Fast data connections seen in laptops and mobile devices.

- Communication interfaces in telecommunication equipment.

Parameter Features

Key characteristics of the DLW21SN371SQ2L include:

- High common mode impedance at relevant frequencies.

- Compact surface-mount design suitable for high-density PCBs.

- Low differential mode impedance to preserve signal integrity.

- Designed to efficiently filter out high-frequency noise.

- Fit for applications requiring high-speed data transmission.

Circuit Connection - USB Interface Noise Suppression

Example application in a USB interface:

Placement Near USB Connector

- Location: Close to the USB data lines on a device's circuit board.

- Purpose: To suppress common mode noise in the USB interface.

- Connection Method: Route the USB D+ and D- data lines through the DLW21SN371SQ2L, connecting each line through one of the two internal filter circuits of the component.

Orientation and Soldering

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

- Purpose: To ensure effective noise suppression.

- Connection Method: Solder the DLW21SN371SQ2L onto the PCB, following the recommended orientation and footprint for optimal performance.

Maintaining Signal Integrity

- Location: Relative to the USB data lines.

- Purpose: To ensure the filter does not degrade the USB data signals.

- Connection Method: Position the DLW21SN371SQ2L at an optimal distance from the USB connector to effectively suppress noise while maintaining signal quality.

Heat Dissipation

- Location: General placement within the circuit.

- Purpose: To maintain component performance and longevity.

- Connection Method: Place the DLW21SN371SQ2L in an area of the PCB with minimal exposure to high temperatures from other components.

Design-Related Issues

When creating circuits with the DLW21SN371SQ2L, take into account: - Impedance Matching: The filter's impedance should be compatible with the USB data lines for effective noise suppression.

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

- Thermal Management: Make sure the choke performs within its temperature range by taking the circuit's thermal environment into account.

- Signal Integrity: Ensure that the placement of the choke maintains the integrity of high-speed data signals.

In conclusion, the DLW21SN371SQ2L is crucial in applications like USB interface noise suppression, where its ability to effectively reduce common mode noise while preserving signal integrity is vital. Proper integration, considering impedance, physical layout, thermal aspects, and signal quality, is key to its successful use in electronic systems.
