Overview
The Würth Elektronik 7446121010 is a current-compensated common mode choke from the WE-LF Type SV series. It features an inductance of 10 mH at 10 kHz, with a maximum DC resistance of 0.55 ohms and a rated DC current of 700 mA. The component supports a rated voltage of 250 VAC and operates within a temperature range starting at -40°C. Designed for through-hole mounting, it utilizes a toroidal core structure to provide effective noise suppression in power line applications.
Feature Summary
- Current-compensated design for efficient common mode noise reduction
- Toroidal core construction for compact form factor
- Through-hole termination for reliable PCB integration
Applications
- Power line filtering in electronic equipment
- EMI suppression in AC/DC converter circuits
- Signal integrity enhancement in sensitive power inputs
Procurement Notes
Verify the specific manufacturing origin, which may be Thailand, against project requirements. Confirm RoHS compliance status and SVHC declarations directly with the manufacturer or authorized distributors prior to procurement. Ensure that the through-hole package dimensions align with the target PCB layout constraints.
Selection Notes
Select this component when a 10 mH inductance value is required for common mode interference mitigation. The 700 mA current rating suits moderate power applications. Consider the 0.55 ohm DC resistance impact on circuit efficiency. The through-hole format dictates specific board space and assembly process considerations compared to surface mount alternatives.
Part Context
This part belongs to the WE-LF series, focusing on power line chokes. It serves as a specialized solution for electromagnetic compatibility challenges in low-frequency environments. The series emphasizes robust performance in industrial and consumer electronics where reliable noise filtering is critical for system stability.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching inductance, current rating, and physical dimensions with other manufacturers' offerings.
