Overview
The Würth Elektronik 744232101 is a surface-mount common mode line filter from the WE-CNSW series, designed for high-frequency noise suppression. It features an inductance of 105.3 µH and offers an impedance of 6 kOhms at 100 MHz. The component supports a maximum DC current of 90 mA with a maximum DC resistance of 6 Ohms. Housed in a compact 1206 (3.2 mm x 1.6 mm x 1.8 mm) package, it operates within a temperature range of -40°C to +125°C. The device is qualified under AEC-Q200 standards for automotive reliability.
Feature Summary
- AEC-Q200 qualified for automotive applications
- High impedance common mode filtering at 100 MHz
- Compact 1206 surface-mount footprint
Applications
- Automotive data line noise suppression
- High-speed signal integrity protection
- Common mode interference reduction in compact electronics
Procurement Notes
Verify the specific impedance value against the official datasheet, as conflicting sources list 6 kOhm or 6000 kOhm. Confirm the package dimensions match the 1206 standard. Ensure the supplier provides the original manufacturer documentation to validate the AEC-Q200 qualification status before integration into critical designs.
Selection Notes
Select this component when high-frequency common mode noise attenuation is required in space-constrained environments. The 1206 package allows for dense PCB layouts. Verify that the 90 mA current rating meets the circuit's operational requirements. The wide operating temperature range ensures stability in demanding thermal conditions.
Part Context
This part belongs to the WE-CNSW series of SMT common mode line filters. These components are engineered for efficient noise suppression in digital and analog circuits. The series emphasizes small form factors combined with robust performance characteristics suitable for modern electronic systems requiring reliable signal integrity.
Replacement Considerations
Check for direct substitutes within the WE-CNSW series with similar impedance and current ratings. Verify pin compatibility and physical dimensions before swapping. Consult the manufacturer's cross-reference guide for validated alternatives.
