DLW5ATN112MQ2L

Common Mode Chokes Overview

The DLW5ATN112MQ2L is a two-line common mode choke manufactured by Murata Electronics, designed for surface-mount PCB assembly. It operates within an impedance range of 1.1 kOhms at 100 MHz and supports a maximum DC current of 1 A. The component features a low maximum DC resistance of 120 mOhms and functions reliably across a temperature span from -40°C to +85°C. Housed in a compact 2014 (5036 metric) package measuring 5 mm x 3.6 mm x 2.2 mm, it utilizes wirewound technology and meets AEC-Q200 automotive qualification standards.
