DLW5ATH331MQ2L

Common Mode Chokes Overview

The DLW5ATH331MQ2L is a wirewound common mode choke from the Murata EMIFIL DLW5A series. It features a single-channel configuration with an impedance of 330 Ohms at 100 MHz and a maximum DC current rating of 2.5 A. The component exhibits a maximum DC resistance of 27 mOhms and operates within a temperature range of -40°C to +125°C. It is housed in a 2014 (5036 metric) surface-mount package measuring 5 mm x 3.6 mm x 2.2 mm. The device holds AEC-Q200 qualification for automotive reliability.

Common Mode Chokes Feature Summary

• Wirewound construction provides high current handling capability for power line filtering applications.
• AEC-Q200 qualification ensures compliance with automotive electronic component stress testing standards.
• Unshielded design allows for flexible PCB layout integration in compact electronic assemblies.

Common Mode Chokes Applications

• Automotive infotainment system noise suppression
• Power supply input filtering for vehicle electronics
• Signal line protection in automotive control units

Common Mode Chokes Procurement Notes

Verify the specific suffix against official Murata documentation to confirm exact electrical tolerances and packaging options. Ensure the procurement channel sources genuine components to maintain AEC-Q200 certification validity. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit risks and confirm current production status before finalizing orders.

Common Mode Chokes Selection Notes

Select this component when a 330 Ohm impedance at 100 MHz is required for common mode noise reduction. The 2.5 A current rating suits moderate power line applications. Verify that the 2014 footprint fits the target PCB design. Confirm that the +125°C operating temperature meets the environmental requirements of the intended installation site.

Common Mode Chokes Part Context

This component belongs to the DLW5A series of chip common mode chokes manufactured by Murata Electronics. The series utilizes wirewound technology to achieve high performance in small surface-mount packages. The DLW5ATH variant specifically denotes the higher temperature rating and automotive qualification within the broader product family.

Common Mode Chokes Replacement Considerations

DLW5ATZ331MQ2L: Similar specifications but rated for +105°C instead of +125°C. DLW5ATN331MQ2L: Higher current rating of 4 A but limited to +105°C operation. Verify thermal constraints before substituting.
