DLW5ATH231TQ2K

Common Mode Chokes Overview

The DLW5ATH231TQ2K is a two-line common mode choke coil from the EMIFIL DLW5A series, manufactured by Murata Electronics. Designed for surface mount PCB assembly, this unshielded wire-wound component measures 5.00 mm in length, 3.60 mm in width, and 2.35 mm in height. It provides an impedance of 230 Ohms at 100 MHz with a maximum DC resistance of 27 mOhms. The device supports a rated DC current of 2.5 A and operates within a temperature range of -40°C to +125°C. It holds AEC-Q200 qualification for automotive reliability.

Common Mode Chokes Feature Summary

• Provides effective electromagnetic interference suppression for power and signal lines through high-impedance common mode noise attenuation.
• Features a low-profile chip design suitable for space-constrained printed circuit board layouts.
• Constructed as an unshielded wire-wound component to minimize parasitic capacitance effects.

Common Mode Chokes Applications

• Automotive electronic systems requiring AEC-Q200 qualified components
• Power line filtering in vehicle infotainment units
• Signal line protection in automotive control modules

Common Mode Chokes Procurement Notes

Verify the specific suffix against official documentation to confirm package type and reel specifications. Confirm availability status as distribution channels may list discontinued or limited stock items. Ensure the ordering code matches the required impedance and current ratings for the target application circuit.

Common Mode Chokes Selection Notes

Select this component when a 230 Ohm impedance at 100 MHz is required for common mode noise reduction. The 2.5 A current rating suits moderate power applications. Verify that the 2.35 mm height fits within the mechanical envelope constraints of the final assembly design.

Common Mode Chokes Part Context

This part belongs to the DLW5A_H series of low-profile chip common mode chokes. It shares the standard 2014 (5036 metric) footprint dimensions with other variants in the family, differing primarily in impedance values and current handling capabilities defined by the manufacturer's catalog.

Common Mode Chokes Replacement Considerations

Check for DLW5ATH231TQ2L if cut tape packaging is preferred over reel. Verify electrical equivalence with DLW5ATZ231TQ2L regarding impedance and current ratings before substitution.
