Common Mode Chokes datasheet and documents for DLW21SR670HQ2L

DLW21SR670HQ2L

Common Mode Chokes Overview

The DLW21SR670HQ2L is a wirewound common mode filter choke from the Murata EMIFIL DLW21 series. It features a single-channel configuration housed in an unshielded 0805 (2012 metric) surface-mount package with dimensions of 2 mm length, 1.2 mm width, and 1.2 mm height. The component exhibits an impedance of 67 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 400 mA and has a maximum DC resistance of 250 mOhms. The device operates within a temperature range of -40°C to +85°C.

Common Mode Chokes Feature Summary

Wirewound construction for effective electromagnetic interference suppression
Unshielded design suitable for standard PCB layouts
Single-channel architecture for signal line filtering

Common Mode Chokes Applications

Signal line noise suppression
Electromagnetic interference filtering in compact electronic devices

Common Mode Chokes Procurement Notes

Verify the specific suffix HQ2L against official Murata documentation to confirm packaging and tape-and-reel specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target circuit. Cross-reference the datasheet revision date to guarantee compliance with current manufacturing standards and RoHS directives before finalizing procurement orders.

Common Mode Chokes Selection Notes

Select this component when a low-profile 0805 footprint is required for high-frequency noise attenuation. The 67 Ohm impedance at 100 MHz targets specific EMI bands. Verify that the 400 mA current rating exceeds the operational peak current. Confirm that the unshielded nature does not interfere with adjacent sensitive components on the board layout.

Common Mode Chokes Part Context

This part belongs to the DLW21 series of chip common mode chokes manufactured by Murata Electronics. The series utilizes wirewound technology to provide noise suppression in small surface-mount packages. These components are designed for use in portable electronics and communication equipment where space constraints limit the use of larger magnetic filters.
