DLW21SN181SQ2L Description

Short technical summary and product information.

The Murata DLW21SN181SQ2L is a chip common mode choke coil designed for signal line filtering. It features a common mode impedance of 180 Ohms ±25% at 100 MHz, with a maximum DC resistance of 350 mOhm and a rated current of 330 mA. The component is rated for 50V DC and has a withstanding voltage of 125V DC. Insulation resistance is 10 MOhm minimum. Operating temperature range is -40°C to +85°C. The device is housed in a horizontal, 4 PC pad surface mount package measuring 2.00mm x 1.20mm with a maximum height of 1.40mm. It is RoHS3 compliant and has an MSL of 1 (unlimited). Typical applications include noise suppression in digital interfaces, USB lines, and other signal lines where common mode noise needs to be attenuated.
