Overview
The Würth Elektronik 744212820 is a surface-mount common mode line filter from the WE-SL1 series. It features an inductance of 82 µH per channel and provides an impedance of 440 Ω at 100 kHz. The component supports a maximum DC current of 300 mA with a maximum DC resistance of 200 mΩ. Designed for PCB mounting, it operates within a temperature range of -40°C to +105°C. The physical dimensions are 6.5 mm in length, 3.6 mm in width, and 1.65 mm in height.
Feature Summary
- Provides effective common mode noise suppression for signal lines
- Supports high impedance filtering at specific frequencies
- Designed for compact surface-mount PCB integration
Applications
- Signal line filtering in electronic circuits
- Noise reduction in data transmission interfaces
- EMI suppression in consumer electronics
Procurement Notes
Verify the exact datasheet version and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the 300 mA current rating and 440 Ω impedance meet the specific circuit requirements. Ensure the operating temperature range aligns with the intended application environment.
Selection Notes
Select this component when a low-profile SMD common mode choke is required for 300 mA applications. The 82 µH inductance and 440 Ω impedance offer a balance between signal integrity and noise attenuation. Consider the 6.5 x 3.6 mm footprint for space-constrained designs requiring reliable EMI performance.
Part Context
This part belongs to the WE-SL1 series of common mode chokes by Würth Elektronik. The series is characterized by its small form factor and suitability for surface-mount technology. These components are engineered to handle moderate currents while providing significant impedance to common mode interference.
Replacement Considerations
Check for direct substitutes within the WE-SL1 series with matching 82 µH inductance and 440 Ω impedance. Verify that any alternative maintains the same 300 mA current rating and compatible physical dimensions for PCB compatibility.
