Overview
The Würth Elektronik 7442335600 is a surface-mount common mode choke from the WE-CNSW HF series, designed for high-frequency signal line filtering. It features two channels with an impedance of 60 Ohms at 100 MHz and a maximum DC current rating of 600 mA. The component has a maximum DC resistance (DCR) of 220 mOhms and operates within a temperature range of -40°C to +105°C. Its compact dimensions are 1.20 mm in length, 1.00 mm in width, and a maximum height of 0.90 mm.
Feature Summary
- High-frequency signal line filtering capability
- Compact surface-mount design for space-constrained applications
- AEC-Q200 qualified for automotive reliability
Applications
- Automotive infotainment systems
- High-speed data interface protection
- Signal line EMI suppression
Procurement Notes
Verify the specific suffix and packaging configuration against the official datasheet before ordering. Confirm that the required impedance and current ratings align with the target circuit design. Ensure compatibility with automated pick-and-place equipment due to the small SMD footprint. Check for any recent production change notices that might affect lead times or material composition.
Selection Notes
Select this component when high-frequency noise suppression is critical for differential signal lines. The low DCR minimizes power loss in the signal path. Consider the 600 mA current rating to ensure it exceeds the peak operating current of the protected circuit. The small package size makes it suitable for dense PCB layouts where larger chokes cannot fit.
Part Context
This part belongs to the WE-CNSW HF series, which specializes in high-frequency common mode chokes. These components are engineered to provide effective EMI/RFI suppression in compact form factors. The series is widely used in automotive and industrial applications requiring reliable signal integrity protection.
Replacement Considerations
Check for direct substitutes within the WE-CNSW series with similar impedance and current ratings. Verify pinout compatibility if replacing in existing designs. Ensure the replacement component meets the same AEC-Q200 qualification standards if used in automotive applications.
