Overview
The Würth Elektronik 744230450 is a WE-CNSW series common mode choke designed for surface mount technology. It features a 0603 (1608 metric) package with dimensions of 1.6 mm length, 0.85 mm width, and 1.1 mm height. The component provides an impedance of 45 Ohms at 100 MHz and has an inductance of 56 nH with a 25% tolerance. It supports a maximum DC current of 650 mA and exhibits a maximum DC resistance of 110 mOhms. Rated for operation between -40°C and +105°C, it holds AEC-Q200 qualification.
Feature Summary
- AEC-Q200 qualified for automotive reliability standards
- Compact 0603 surface mount footprint for space-constrained designs
- High impedance performance at 100 MHz for effective noise suppression
Applications
- Automotive electronic circuit protection
- Signal line filtering in compact devices
- EMI suppression in mobile hardware
Procurement Notes
Verify the specific ordering suffix to ensure the correct packaging configuration matches your assembly requirements. Confirm that the AEC-Q200 certification status remains active for your intended automotive application. Cross-reference the 0603 package dimensions against your PCB land pattern to guarantee mechanical compatibility during placement.
Selection Notes
Select this component when a small form factor is required alongside moderate current handling capabilities. The 650 mA rating suits low-power signal lines rather than high-current power rails. Ensure the 45 Ohm impedance at 100 MHz aligns with the target frequency spectrum of the interference you intend to filter within your circuit design.
Part Context
This part belongs to the WE-CNSW series from Würth Elektronik, which specializes in surface mount common mode chokes. The series offers various impedance and current ratings across different package sizes to support diverse EMI filtering needs in modern electronics manufacturing.
Replacement Considerations
Consult official Wurth Elektronik documentation for verified cross-references. No public substitute part numbers are confirmed in the provided source material.
