Overview
The Würth Elektronik 744235101 is a surface-mount common mode line filter from the WE-CNSW series. It features an inductance of 100 µH and an impedance of 5 kΩ at 100 MHz. The component supports a rated current of 150 mA with a DC resistance of 2 Ω. It operates within a temperature range of -40°C to +125°C and holds AEC-Q200 qualification. The physical dimensions are 4.5 mm x 3.2 mm x 2.7 mm, designed for PCB mounting.
Feature Summary
- AEC-Q200 qualified for automotive reliability standards
- High impedance performance at 100 MHz for effective noise suppression
- Compact surface-mount package suitable for space-constrained designs
Applications
- Automotive data line filtering
- Common mode noise suppression in electronic circuits
- Signal integrity protection in high-speed interfaces
Procurement Notes
Verify the specific datasheet version for the 744235101 part number to confirm exact electrical tolerances and packaging options. Ensure compatibility with automated pick-and-place equipment regarding the 0805-style footprint dimensions. Cross-reference the AEC-Q200 certification status if the application requires strict automotive compliance documentation.
Selection Notes
Select this component when high common mode rejection is required at 100 MHz with limited current capacity. The 100 µH inductance provides significant attenuation for differential noise while maintaining signal integrity. Consider the 2 Ω DC resistance impact on power delivery if used in low-voltage sensitive lines.
Part Context
This component belongs to the WE-CNSW series of SMD common mode line filters manufactured by Würth Elektronik. The series is characterized by its small form factor and high impedance characteristics, making it suitable for modern electronics requiring efficient EMI mitigation without occupying excessive board space.
Replacement Considerations
Check for direct substitutes within the WE-CNSW series that offer similar impedance curves. Verify pinout compatibility and thermal performance before substituting with components from other manufacturers.
