744862033

Overview

The Würth Elektronik 744862033 is a through-hole common mode choke from the WE-TFC series. It features a current-compensated design with an inductance of 3.3 mH at 10 kHz and a rated current of 800 mA. The component has a maximum DC resistance of 510 mOhm and utilizes a ceramic core material. It is housed in a standard through-hole package suitable for power line filtering applications.

Feature Summary

• Current-compensated choke architecture for effective noise suppression
• High inductance value optimized for low-frequency interference
• Through-hole mounting configuration for robust PCB integration

Applications

• Power line filtering
• EMI suppression in electronic circuits
• Common mode noise reduction in signal lines

Procurement Notes

Verify the specific datasheet version to confirm mechanical dimensions and thermal characteristics before finalizing the design. Ensure that the through-hole footprint matches the target PCB layout. Confirm compliance with relevant environmental regulations such as RoHS if required by the end product specifications.

Selection Notes

Select this component when high inductance is required for low-frequency common mode noise attenuation. The 800 mA rating suits moderate current applications. Consider the through-hole form factor if automated surface-mount assembly is not available or if higher mechanical stability is needed compared to SMD alternatives.
