Overview
The Würth Elektronik 7446721010 is a through-hole common mode choke from the WE-LF series, designed for line filtering applications. It features an inductance of 10 mH with a tolerance of 30%. The component supports a maximum DC current of 1.3 A and has a maximum DC resistance of 250 mOhms. It operates within a temperature range of -40°C to +125°C. The device utilizes a two-line configuration for effective noise suppression.
Feature Summary
- Provides common mode noise attenuation for differential signal lines
- Utilizes a robust through-hole mounting style for secure PCB attachment
- Constructed with a ferrite core to enhance magnetic performance
Applications
- Line filtering in power supply circuits
- Noise suppression in data communication interfaces
- EMI reduction in industrial control systems
Procurement Notes
Verify the specific electrical parameters against the official manufacturer datasheet before integration. Confirm that the through-hole package dimensions align with the target PCB footprint. Ensure the selected component meets the required thermal and current ratings for the intended operational environment. Cross-reference the part number to avoid confusion with similar series variants.
Selection Notes
Select this component when high inductance values are required for low-frequency noise filtering. The through-hole construction offers mechanical stability compared to surface-mount alternatives. Consider the 1.3 A current rating to ensure adequate headroom for peak load conditions. Evaluate the physical size constraints as through-hole components typically require larger board real estate.
Part Context
This component belongs to the WE-LF series of common mode chokes manufactured by Würth Elektronik. The series is engineered for general-purpose EMI suppression tasks. It complements the manufacturer's broader portfolio of passive components used in power management and signal integrity solutions.
Replacement Considerations
Direct substitutes include other 10 mH common mode chokes with comparable current ratings and through-hole packages. Verify pin compatibility and inductance tolerance before substitution. Alternative parts must meet the same thermal and electrical specifications to maintain circuit performance.
