Overview
The Würth Elektronik 744252220 is a surface-mount common mode line filter from the WE-SL3 series. It features an inductance of 22 µH at 100 kHz and supports a maximum DC current of 700 mA. The component has a maximum DC resistance of 0.14 Ohms and an impedance of 1.6 kOhms. Rated for 80 V DC, it operates within a temperature range of -40°C to +125°C. The physical dimensions are 9.2 mm x 6.6 mm x 2.5 mm.
Feature Summary
- Compact surface-mount design for high-frequency noise reduction
- Dual-line configuration for effective EMC filtering
- Robust thermal performance across extended industrial temperatures
Applications
- EMC filtering in industrial communication systems
- High-frequency noise suppression in signal lines
- Common mode interference mitigation in compact electronics
Procurement Notes
Verify the specific manufacturer part number against official Wurth Elektronik documentation to ensure authenticity. Confirm that the received components match the WE-SL3 series specifications, including the 22 µH inductance and 700 mA current rating. Check for RoHS compliance status as indicated in the official datasheet before integration into production.
Selection Notes
Select this component when a low-profile SMD common mode choke is required for signal line filtering. The 700 mA rating suits moderate current applications, while the 0.14 Ohm DCR minimizes power loss. Ensure the PCB footprint accommodates the 9.2 mm x 6.6 mm package and that the operating environment stays within the specified -40°C to +125°C range.
Part Context
This component belongs to the WE-SL3 series of surface-mount common mode filters. These devices are engineered for space-constrained designs requiring efficient electromagnetic compatibility solutions. The series utilizes ferrite core technology to provide stable inductance characteristics across varying frequencies and temperatures.
Replacement Considerations
Consult official Wurth Elektronik substitution guides for verified alternatives. Cross-reference key parameters such as inductance, current rating, and physical dimensions to ensure functional equivalence without compromising circuit performance or board layout constraints.
