Common Mode Chokes datasheet and documents for DLW21HN900SQ2L

DLW21HN900SQ2L

Common Mode Chokes Overview

The DLW21HN900SQ2L is a wirewound common mode choke from the Murata EMIFIL DLW21 series. It features a 0805 (2012 metric) surface mount package with dimensions of 2 mm x 1.2 mm x 0.9 mm. The component provides an impedance of 90 Ohms at a test frequency of 100 MHz, with a tolerance of ±25%. It supports a maximum DC current of 330 mA and has a maximum DC resistance of 350 mOhms. Rated for 50 VDC, it operates within a temperature range of -40°C to +85°C.

Common Mode Chokes Feature Summary

High coupling coefficient design suppresses noise on differential signal lines without causing distortion in high-speed data transmission.
Wirewound construction delivers high common-mode impedance for effective electromagnetic interference suppression.
Compact molded case structure enables reliable PCB mounting in space-constrained applications.

Common Mode Chokes Applications

Noise suppression for USB lines in personal computers and peripheral devices
Signal integrity protection for LVDS lines in notebook PCs
EMI filtering for LCD panels and small digital AV equipment such as digital cameras

Common Mode Chokes Procurement Notes

Verify the complete part number against official Murata documentation to ensure correct suffix identification. Confirm that the specific variant matches the required impedance tolerance and current rating for the target circuit. Cross-reference the package dimensions and terminal configuration with the layout footprint to prevent assembly errors during production integration.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring compact EMI filtering for high-speed differential signals like USB or LVDS. Ensure the operating environment stays within the specified -40°C to +85°C range. Verify that the 330 mA current rating exceeds the maximum expected load current to maintain performance and prevent saturation effects during normal operation.

Common Mode Chokes Part Context

This component belongs to the Murata DLW21 series of unshielded common mode chokes. The series utilizes wirewound technology to achieve high coupling coefficients suitable for suppressing noise on high-speed data lines. These components are designed for surface mount installation and are widely used in consumer electronics and portable devices where space efficiency and signal integrity are critical requirements.

Common Mode Chokes Replacement Considerations

Consult official Murata substitution guides for verified alternatives. Do not assume functional equivalence with other series based solely on package size or nominal impedance values. Verify electrical parameters and thermal characteristics before implementing any substitute component in the design.
