744824220

Overview

The Würth Elektronik part number 744824220 is a through-hole common mode choke belonging to the WE-CMB series. It features a manganese zinc core material and provides an inductance of 20 mH at a test frequency of 10 kHz. The component supports a maximum DC current rating of 2 A and has a maximum DC resistance of 0.22 ohms. It is designed for operation within a temperature range of -40°C to +125°C and carries a voltage rating of 250 V ac.

Feature Summary

Utilizes manganese zinc core technology for effective noise suppression
Through-hole construction suitable for robust PCB mounting
Designed for common mode noise and radio interference reduction

Applications

Motor drive noise suppression
Radio interference suppression in motor applications
Common mode noise filtering in power lines

Procurement Notes

Verify the specific manufacturer datasheet for the 744824220 component to confirm all electrical parameters, mechanical dimensions, and compliance certifications before integration. Ensure that the through-hole package style matches the target PCB footprint design requirements. Cross-reference official documentation to validate the operating temperature range and current ratings against the specific application constraints.

Selection Notes

Select this component when a through-hole common mode choke with high inductance is required for motor or power line applications. The 20 mH value and 2 A current rating make it suitable for suppressing significant common mode noise. Consider the physical size and leaded package type compared to surface mount alternatives if space or mounting method is a constraint.
