744824310

Overview

The Würth Elektronik WE-CMB 744824310 is a radial common mode choke designed for power line filtering. It features a manganese zinc core and offers an inductance of 10 mH at 10 kHz with a tolerance of ±25%. The component supports a maximum DC current of 3 A and has a maximum DC resistance of 105 mΩ. Rated for 250 VAC, it operates within a temperature range of -40°C to +105°C. The device utilizes broadband screening due to low capacitance winding techniques.

Feature Summary

• Broadband screening capability achieved through low capacitance winding techniques
• Very compact design suitable for space-constrained applications
• High current handling capacity for power line protection

Applications

• Power line noise suppression
• Common-mode noise filtering in electronic circuits
• EMI reduction in AC power inputs

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the radial lead configuration matches your PCB footprint requirements. Ensure the operating environment stays within the specified -40°C to +105°C temperature range to maintain performance integrity and reliability standards.

Selection Notes

Select this component when broadband EMI suppression is required for AC power lines up to 250 VAC. The 3 A current rating makes it suitable for moderate power applications. Consider the radial package for through-hole mounting. Evaluate the 10 mH inductance value against the target noise frequency spectrum to ensure effective attenuation characteristics are met for the specific application needs.
