DLW44SN251SK2L

Common Mode Chokes Overview

The DLW44SN251SK2L is a two-line common mode choke manufactured by Murata Electronics, designed for surface mount applications. It features an impedance of 250 Ohms at 100 MHz and supports a maximum DC current of 2.6A. The component has a maximum DC resistance (DCR) of 33.6 milliohms and operates within a temperature range of -40°C to 105°C. Its physical dimensions are 4.00mm x 4.00mm x 1.50mm, housed in a horizontal 4-pin package with a rated DC voltage of 60V.

Common Mode Chokes Feature Summary

• Provides effective noise suppression for differential signal lines through high common mode impedance.
• Supports high current handling capabilities suitable for power line filtering applications.
• Utilizes a compact surface mount footprint to facilitate automated PCB assembly processes.

Common Mode Chokes Applications

• Noise suppression on USB data lines
• EMI filtering for HDMI interfaces
• Signal integrity enhancement in high-speed digital circuits

Common Mode Chokes Procurement Notes

Verify the specific suffix codes against official Murata documentation to ensure correct impedance and tolerance specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Check for obsolescence notices as distributor listings may indicate discontinuation status. Ensure packaging format matches production line capabilities.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring robust common mode noise rejection for dual-line interfaces. Evaluate the 2.6A current rating against peak operational loads to prevent saturation. Consider the 4.00mm x 4.00mm package size for space-constrained layouts. Verify that the 250 Ohm impedance at 100 MHz aligns with the target frequency spectrum of interference sources.

Common Mode Chokes Part Context

This part belongs to the DLW44SN series of wirewound common mode chokes from Murata. The series is characterized by low DCR and high current capacity, making it distinct from lower-current signal filters. It shares dimensional similarities with other DLW44 variants but differs in electrical parameters based on the impedance coding within the part number.

Common Mode Chokes Replacement Considerations

Consult official Murata substitution guides for verified equivalents. Cross-reference impedance values and current ratings carefully. Do not assume pin compatibility without verifying mechanical drawings of potential substitutes.
