DLW32SH220XK2L

Common Mode Chokes Overview

The DLW32SH220XK2L is a two-channel common mode choke manufactured by Murata Electronics, designed for surface mount PCB integration. It features a wirewound construction within a 1210 (3225 metric) package measuring 3.2 mm in length, 2.5 mm in width, and 2.35 mm in height. The component provides an inductance of 22 µH at a test frequency of 100 kHz with a tolerance range of -30% to +50%. It supports a maximum DC current of 250 mA and exhibits a maximum DC resistance of 500 mOhms. The device operates reliably between -40°C and +125°C and holds AEC-Q200 qualification.

Common Mode Chokes Feature Summary

• Provides effective common mode noise suppression through dual-line filtering architecture
• Utilizes wirewound technology for stable inductive performance in compact form factors
• Engineered for automotive reliability with AEC-Q200 certification compliance

Common Mode Chokes Applications

• Automotive electronic circuit noise filtering
• Signal line protection in surface mount assemblies
• Common mode interference reduction in data transmission interfaces

Common Mode Chokes Procurement Notes

Verify the specific suffix codes against official Murata documentation to confirm exact electrical tolerances and packaging configurations. Ensure that the selected variant matches the required inductance values and current ratings for the target application environment. Cross-reference the manufacturing date codes and RoHS compliance status with the latest distributor catalogs to guarantee material consistency and supply chain authenticity.

Common Mode Chokes Selection Notes

Select this component when a compact 1210 footprint is required for dual-line noise suppression in space-constrained designs. The 250 mA current rating suits low-power signal lines rather than high-current power rails. Consider the -30% to +50% inductance tolerance during circuit simulation to ensure adequate noise attenuation across the full production variance. Verify thermal management requirements given the unshielded construction and operating temperature limits.

Common Mode Chokes Part Context

This component belongs to the DLW32SH series of common mode chokes from Murata Electronics. The series utilizes wirewound technology to deliver reliable electromagnetic interference suppression in small surface-mount packages. These devices are engineered for high-volume manufacturing processes and are widely integrated into automotive and industrial electronics where robust noise filtering is critical for signal integrity.

Common Mode Chokes Replacement Considerations

Consult official Murata substitution guides for verified alternatives. Generic equivalents may not match the precise inductance tolerance or AEC-Q200 automotive qualification standards required for this specific application.
