DLW32PH122XK2L

Common Mode Chokes Overview

The DLW32PH122XK2L is a two-channel common mode choke manufactured by Murata Electronics, designed for surface-mount PCB assembly. It belongs to the EMIFIL POWRTRN series and features wire-wound construction within an unshielded 1210 (3225 metric) package measuring 3.2 mm in length, 2.5 mm in width, and 2.35 mm in height. The component exhibits a nominal impedance of 1200 ohms at a test frequency of 100 MHz with a tolerance of plus or minus 20 percent. It supports a maximum DC current of 1200 mA and maintains a maximum DC resistance of 60 milliohms. Rated for operation between negative 40 degrees Celsius and positive 125 degrees Celsius, it holds AEC-Q200 qualification.

Common Mode Chokes Feature Summary

• Provides effective suppression of electromagnetic interference through high-impedance common mode noise filtering capabilities.
• Supports high-current applications via robust wire-wound architecture capable of handling significant direct current loads.
• Ensures reliability in automotive environments through formal AEC-Q200 qualification standards.

Common Mode Chokes Applications

• Automotive infotainment system signal line protection
• High-speed data interface noise suppression in vehicle electronics
• Power line filtering for automotive control modules

Common Mode Chokes Procurement Notes

Verify the specific suffix against official Murata documentation to confirm exact electrical tolerances and packaging configurations. Ensure the procurement channel provides valid traceability records for AEC-Q200 certified components. Confirm that the delivered units match the specified 1210 footprint dimensions and terminal type for proper PCB integration.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring high current capacity alongside substantial common mode noise attenuation. The 1210 package offers a balance between physical size and power handling compared to smaller footprints. Consider the unshielded nature of the design regarding potential magnetic coupling effects in dense layouts.

Common Mode Chokes Part Context

This part belongs to the DLW32PH series, which focuses on high-power common mode chokes. Unlike standard signal filters, this series emphasizes durability under high current conditions while maintaining impedance characteristics suitable for automotive-grade electronic systems.

Common Mode Chokes Replacement Considerations

Consult official Murata substitution guides for compatible alternatives within the DLW32PH family. Verify that any substitute maintains identical impedance curves, current ratings, and mechanical dimensions to ensure circuit compatibility.
