• Features a low profile design suitable for space-constrained PCB layouts
• Supports high rated DC currents ranging up to 4A within the series

Common Mode Chokes Applications

• Automotive electronic systems requiring AEC-Q200 qualified components
• Suppression of electromagnetic interference in data transmission lines
• Filtering noise in power supply circuits for sensitive electronics

Common Mode Chokes Procurement Notes

Verify the complete part number including suffixes against official Murata documentation to ensure correct impedance and tolerance specifications. Confirm that the required packaging format matches your assembly line capabilities, as availability varies between reel, cut tape, and other formats. Ensure the selected variant meets the specific thermal and current requirements of your target application environment.

Common Mode Chokes Selection Notes

Select this component when a compact 5050 footprint is required alongside high current handling capabilities. The 250 Ohm impedance value is suitable for specific frequency bands where moderate attenuation is needed. Consider the 20 mOhms DCR for minimal voltage drop in high-current paths. Verify that the unshielded construction does not interfere with nearby sensitive components or trace routing on the final PCB layout.

Common Mode Chokes Part Context

This component belongs to the DLW5B series of wirewound chip common mode chokes manufactured by Murata Electronics. The series is characterized by its small size relative to its current carrying capacity and impedance performance. These devices are designed for surface mount technology and are widely used in consumer, industrial, and automotive applications for noise suppression.

Common Mode Chokes Replacement Considerations

Check for alternative part numbers within the DLW5B family that offer different impedance values if system requirements change. Verify pin compatibility and physical dimensions before substituting with components from other manufacturers to ensure proper fit and function.
