DLW5BTN251SQ2L

Common Mode Chokes Overview

The DLW5BTN251SQ2L is a two-line common mode choke manufactured by Murata Electronics, designed for surface-mount PCB assembly. It features an impedance of 250 Ohms at 100 MHz and supports a maximum DC current of 5 A with a typical DC resistance of 14 mOhms. The component operates within a temperature range of -40°C to +85°C and utilizes a wirewound construction in an unshielded configuration. Its physical dimensions are 5 mm in length, 3.6 mm in width, and 2.2 mm in height, fitting the standard 1411 metric package.

Common Mode Chokes Feature Summary

• Provides effective noise suppression for differential signal lines through high-impedance common mode attenuation.
• Supports high-current applications up to 5 A with low series resistance to minimize power loss.
• Utilizes a compact wirewound structure suitable for space-constrained surface-mount layouts.

Common Mode Chokes Applications

• High-speed data interface noise filtering
• Power line EMI suppression in industrial equipment
• Signal integrity enhancement in automotive electronics

Common Mode Chokes Procurement Notes

Verify the specific suffix SQ2L against official Murata documentation to confirm package and tape specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target circuit design. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Common Mode Chokes Selection Notes

Select this component when a 250 Ohm impedance at 100 MHz is required for common mode noise reduction. The 5 A current rating makes it suitable for power lines or high-bandwidth data buses. Confirm that the 1411 footprint and unshielded design align with the PCB layout constraints and electromagnetic compatibility requirements of the system.

Common Mode Chokes Part Context

This component belongs to the EMIFIL DLW5B series of common mode chokes from Murata Electronics. The series offers various impedance and current ratings in standardized surface-mount packages. The DLW5BTN251SQ2L specifically targets applications requiring robust noise filtering with moderate physical size and high current handling capabilities.

Common Mode Chokes Replacement Considerations

Consult Murata's official substitution guide for verified alternatives. Check for equivalent impedance, current rating, and package dimensions. Do not assume cross-compatibility with other series without verifying electrical parameters and mechanical fit.
