Overview
The Würth Elektronik 744272221 is a surface mount common mode line filter from the WE-SL5 series. It features a ferrite core and sectional winding structure with an inductance of 220 μH per line at 100 kHz. The component supports a maximum DC current of 2.2 A and exhibits a typical DC resistance of 32 mΩ. It provides a common mode impedance of 780 Ω at 15 MHz. The device operates within a temperature range of -40°C to +125°C and measures 10 mm x 8.7 mm x 6.5 mm.
Feature Summary
- Utilizes sectional winding technology for enhanced performance
- Constructed with a ferrite core material
- Designed for surface mount assembly
Applications
- Common mode noise suppression in electronic circuits
- Signal integrity protection in high-speed data lines
- EMI filtering in power supply inputs
Procurement Notes
Verify the complete part number including any suffixes against official Wurth Elektronik documentation to ensure correct specifications. Confirm that the required inductance tolerance and current ratings align with the design requirements before procurement. Check for RoHS compliance status if mandated by specific regional regulations or customer standards.
Selection Notes
Select this component when a 220 μH common mode choke with 2.2 A current handling is required. Ensure the PCB footprint accommodates the 10 mm x 8.7 mm dimensions. Consider the 32 mΩ DC resistance impact on voltage drop if used in low-voltage applications. Verify thermal management capabilities given the 125°C maximum operating temperature limit.
Part Context
This component belongs to the WE-SL5 series of surface mount common mode chokes. The series is characterized by its sectional winding construction, which distinguishes it from traditional wound inductors. These filters are engineered for effective electromagnetic interference reduction in compact electronic designs requiring reliable noise suppression.
Replacement Considerations
Cross-reference with other WE-SL5 variants such as 744272222 for different inductance values. Ensure substitute components match the 10x8.7x6.5mm package dimensions and 2.2A current rating. Verify compatibility with existing PCB layouts and soldering profiles.
