Overview
The Würth Elektronik 7446620015 is a through-hole common mode choke from the WE-LF series, designed for mains power line filtering. It features an inductance of 15 mH at 10 kHz with a tolerance of 30%. The component supports a maximum DC current of 500 mA and has a maximum DC resistance of 0.83 Ohms. Rated for AC voltages up to 250 V, it operates within a temperature range of -40°C to +125°C. The shielded design measures 18.00 mm x 18.00 mm x 13.00 mm.
Feature Summary
- Provides effective common mode noise suppression for single-phase AC power lines
- Features a shielded construction to minimize electromagnetic interference
- Supports high voltage ratings suitable for direct mains connection applications
Applications
- EMI filtering for single-phase AC power inputs
- Noise suppression in household appliance power supplies
- Line filtering for industrial control equipment AC interfaces
Procurement Notes
Verify the specific suffix codes against official Wurth Elektronik documentation to confirm exact electrical tolerances and packaging configurations. Ensure the selected variant matches the required AC voltage rating and current handling capabilities for the target circuit. Cross-reference the datasheet revision date to guarantee compliance with current RoHS3 standards and material declarations before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring robust common mode noise attenuation for 250 VAC systems. The 15 mH inductance value offers significant impedance at low frequencies, making it suitable for suppressing conducted emissions. Consider the 500 mA current rating to ensure the choke does not saturate under peak load conditions while maintaining thermal stability within the specified operating temperature range.
Part Context
This part belongs to the WE-LF series of common mode chokes specifically engineered for mains power line applications. The series is characterized by its compact horizontal footprint and high reliability for permanent installation in AC power stages. It complements other passive components in EMI filter networks to meet regulatory emission standards for electronic equipment connected to public power grids.
Replacement Considerations
Official substitutes include 7446620039 (39 mH) and 7446621010 (10 mH) from the same WE-LF series. These alternatives share identical mechanical dimensions and mounting styles but differ in inductance values. Verify that the alternative inductance meets the specific filtering requirements of the application circuit.
