DLW5ATH111TQ2L

Common Mode Chokes Overview

The DLW5ATH111TQ2L is a two-line common mode choke from the Murata EMIFIL DLW5A_H series, designed for surface mount PCB integration. It exhibits an impedance of 110 Ohms at 100 MHz and supports a maximum DC current of 3 A with a maximum DC resistance of 20 mOhms. The component operates within a temperature range of -40°C to +125°C and holds AEC-Q200 qualification. Its physical dimensions are 5 mm in length, 3.6 mm in width, and 2.2 mm in height.

Common Mode Chokes Feature Summary

• Provides effective suppression of common mode noise in high-current power lines through wirewound construction.
• Meets automotive reliability standards via AEC-Q200 certification for robust performance in demanding environments.
• Enables compact circuit board layouts due to its small surface-mount footprint and low profile design.

Common Mode Chokes Applications

• Automotive powertrain systems requiring EMI filtering
• Vehicle safety electronics circuits
• High-current DC power line protection

Common Mode Chokes Procurement Notes

Verify the specific suffix against official Murata documentation to confirm exact electrical characteristics and packaging options. Ensure the selected variant matches the required impedance and current ratings for the target application. Confirm compliance with RoHS and REACH regulations as specified in the manufacturer's datasheet before finalizing procurement orders.

Common Mode Chokes Selection Notes

Select this component when designing circuits that require handling up to 3 A of direct current while maintaining low insertion loss. The 110 Ohm impedance rating is suitable for filtering applications at 100 MHz. Consider the 125°C maximum operating temperature for thermal management in enclosed automotive or industrial enclosures where ambient temperatures may be elevated.

Common Mode Chokes Part Context

This component belongs to the DLW5A_H series of chip inductors manufactured by Murata Electronics under the EMIFIL brand. The series is specifically engineered for automotive applications, offering a balance of high current handling capabilities and effective electromagnetic interference suppression in a standardized surface-mount package format.

Common Mode Chokes Replacement Considerations

Consult official Murata documentation for verified substitute part numbers within the same series or compatible alternatives. Do not assume interchangeability based on similar physical dimensions alone; verify electrical parameters such as impedance and saturation current carefully.
