Overview
The Würth Elektronik 7446722007 is a through-hole common mode filter choke from the WE-LF series. It features an inductance of 6.8 mH with a tolerance of ±30%. The component supports a rated current of 1.5 A and has a maximum DC resistance of 0.2 ohms. It operates within a temperature range of -40°C to +125°C and is rated for 250 VAC.
Feature Summary
- Provides effective common mode noise suppression for power line filtering applications.
- Constructed with a toroidal core design for efficient magnetic field containment.
- Designed for PCB mounting via through-hole termination style.
Applications
- Power supply input filtering
- EMI suppression in AC/DC converters
- Noise reduction in industrial control circuits
Procurement Notes
Verify the specific datasheet version for the 7446722007 to confirm mechanical dimensions and pin compatibility before integration. Ensure that the selected manufacturing lot meets the required RoHS compliance standards for your region. Cross-reference the thermal derating curves with your system's ambient operating conditions to guarantee long-term reliability under load.
Selection Notes
Select this component when high inductance values are required for low-frequency noise attenuation in single-phase AC lines. The 1.5 A current rating suits moderate power applications, while the 0.2 ohm DCR minimizes voltage drop. Consider the through-hole package if mechanical stability against vibration is prioritized over compact surface-mount solutions.
Part Context
This part belongs to the WE-LF series of common mode chokes manufactured by Würth Elektronik. The series focuses on providing robust EMI filtering solutions for various electronic equipment. The 7446722007 specifically addresses needs for higher inductance values compared to standard signal line filters, making it suitable for primary side filtering tasks.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with alternative manufacturers based on identical electrical parameters such as 6.8 mH inductance, 1.5 A current rating, and 0.2 ohm resistance.
