Common Mode Chokes datasheet and documents for DLW21SN181XQ2L

DLW21SN181XQ2L

Common Mode Chokes Overview

The DLW21SN181XQ2L is a surface-mount common mode filter manufactured by Murata Electronics. It features a wirewound construction within an unshielded 0805 (2012 metric) package measuring 2.0 x 1.2 x 1.2 mm. The component provides an impedance of 180 Ohms at 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 240 mA and has a maximum DC resistance of 390 mOhms. Rated for voltages up to 50 V DC, it operates reliably across a temperature range of -40°C to +105°C.

Common Mode Chokes Feature Summary

Wirewound technology ensures stable electromagnetic interference suppression in compact layouts
Unshielded design facilitates flexible printed circuit board routing without magnetic interference concerns
AEC-Q200 qualification confirms suitability for demanding automotive electronic environments

Common Mode Chokes Applications

Automotive infotainment system signal line protection
On-board network data bus filtering
Consumer electronics interface noise reduction

Common Mode Chokes Procurement Notes

Verify the specific suffix 'SQ2L' against official Murata documentation to confirm packaging and reel specifications. Ensure that the selected variant matches the required AEC-Q200 automotive grade if intended for vehicle applications. Cross-reference the impedance value and current rating with the target circuit design to prevent performance degradation under load conditions.

Common Mode Chokes Selection Notes

Select this component when space constraints require a 0805 footprint with high current handling capabilities. The 240 mA rating distinguishes it from lower-current alternatives in the same series. Consider the unshielded nature for applications where magnetic coupling with nearby components must be minimized or managed through layout spacing.

Common Mode Chokes Part Context

This part belongs to the EMIFIL DLW21 series, designed for high-density mounting on modern printed circuit boards. The series offers various impedance values tailored for different frequency ranges. The SN suffix indicates specific electrical characteristics and packaging options distinct from other variants like HN or SZ.
