Overview
The Würth Elektronik 744252101 is a surface-mount common mode line filter from the WE-SL3 series. It features an inductance of 100 µH and offers an impedance of 5 kΩ at 1 kHz. The component supports a maximum DC current of 500 mA with a maximum DC resistance of 0.28 Ω. Designed for robust operation, it functions within a temperature range of -40 °C to +125 °C. The physical dimensions are 9.2 mm in length, 6.6 mm in width, and 2.5 mm in height.
Feature Summary
- Provides effective noise suppression through high common mode impedance characteristics
- Utilizes a compact surface-mount housing suitable for automated PCB assembly processes
- Engineered to minimize stray or leakage inductance for signal integrity
Applications
- EMI filtering in digital communication interfaces
- Noise suppression for data bus lines
- Signal conditioning in industrial control systems
Procurement Notes
Verify the specific manufacturer part number against official Wurth Elektronik documentation to ensure authenticity. Confirm that the received components match the specified electrical parameters and physical dimensions. Check for compliance with relevant environmental standards such as RoHS and REACH requirements before integration into final assemblies.
Selection Notes
Select this component when a 100 µH inductance and 500 mA current rating are required for common mode noise reduction. Ensure the 9.2 mm x 6.6 mm footprint fits the available PCB real estate. Consider the 0.28 Ω DC resistance impact on circuit efficiency and verify thermal performance within the -40 °C to +125 °C operating range.
Part Context
This component belongs to the WE-SL3 series of surface-mount common mode chokes. The series provides various inductance values and current ratings to suit different filtering needs. These filters are designed for applications requiring reliable noise attenuation in space-constrained electronic environments.
Replacement Considerations
Consult official Wurth Elektronik cross-reference lists for verified substitutes. Ensure any replacement matches the 100 µH inductance, 500 mA current rating, and 5 kΩ impedance specifications.
