744235251

Overview

The Würth Elektronik 744235251 is a surface-mount common mode line filter from the WE-CNSW series. It features an inductance of 250 µH and a DC resistance of 1.6 ohms. The component supports a maximum current of 200 mA and operates within a temperature range of -40°C to +125°C. Its physical dimensions are 4.5 mm x 3.2 mm x 2.8 mm, with an unshielded design suitable for signal line applications.

Feature Summary

Provides common mode noise suppression for signal lines
AEC-Q200 qualified for automotive reliability standards
Compact surface-mount footprint for space-constrained designs

Applications

Automotive electronic systems requiring EMI filtering
Signal line protection in data communication interfaces
Noise suppression in compact consumer electronics

Procurement Notes

Verify the specific AEC-Q200 qualification status and exact impedance characteristics against the official manufacturer datasheet before integration. Confirm that the 200 mA current rating aligns with your circuit's operational requirements. Ensure the unshielded package type meets your electromagnetic interference mitigation strategy. Cross-reference the part number with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when a low-profile, automotive-grade common mode choke is required for signal lines. The 250 µH inductance offers effective filtering for specific frequency ranges. Consider the 1.6 ohm DC resistance impact on signal integrity. The unshielded construction may require careful PCB layout to minimize crosstalk. Verify compatibility with automated pick-and-place equipment due to the small SMD package size.

Part Context

This component belongs to the WE-CNSW series of surface-mount common mode chokes. The series is designed for high-reliability applications, particularly in the automotive sector. The 744235251 variant specifically targets signal line filtering needs where space is limited but robust noise suppression is essential. It complements other components in power management and data transmission circuits.
