Overview
The Würth Elektronik 7446822006 is a current-compensated common mode choke from the WE-LF Type LH series. It features a 5.6 mH inductance with a 30% tolerance and a rated current of 2 A. The component has a maximum DC resistance of 160 mOhms and operates within a temperature range of -40°C to +125°C. Its self-resonant frequency is 7 MHz. The physical dimensions are 10.5 mm in length, 9.5 mm in width, and 10.5 mm in height, utilizing a ferrite core and standard radial leads.
Feature Summary
- Current-compensated design for balanced signal integrity
- Shielded construction to minimize electromagnetic interference
- High saturation current capability for power line filtering
Applications
- DC-DC converter input/output filtering
- Power supply noise suppression
- Automotive electronics EMI mitigation
Procurement Notes
Verify the specific lead time and availability status directly with authorized distributors or the manufacturer before finalizing procurement plans. Confirm that the ordering suffix matches the required pin configuration and packaging format. Ensure compliance with RoHS directives and check for any recent product lifecycle changes or obsolescence notices.
Selection Notes
Select this component when a current-compensated common mode choke is required for applications demanding high saturation current and low DC resistance. The 5.6 mH value suits general-purpose power line filtering where balanced impedance is critical. Consider the 160 mOhms DCR for efficiency calculations and ensure the 2A rating aligns with the circuit's maximum operating current.
Part Context
This part belongs to the WE-LF Type LH series of current-compensated chokes by Würth Elektronik. These components are designed for robust performance in noisy environments, offering superior common mode rejection compared to standard chokes. The series is widely used in industrial and automotive sectors for its reliability and compact form factor.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by comparing inductance, current ratings, and physical dimensions before considering alternative components.
