744844102

Overview

The Würth Elektronik 744844102 is a WE-ExB series common mode power line choke designed for through-hole mounting. It features an inductance of 1000 µH (1 mH) at 10 kHz with a tolerance of ±30%. The component supports a maximum DC current rating of 4.5 A and has a maximum DC resistance of 42 mΩ. It operates within a temperature range of -40°C to +125°C and is rated for 250 V AC.

Feature Summary

Provides effective common mode noise suppression for power lines
Designed for robust through-hole installation on printed circuit boards
Utilizes NiZn core material for stable performance across operating temperatures

Applications

Power supply input filtering
EMI suppression in industrial equipment
Noise reduction in consumer electronics power stages

Procurement Notes

Verify the specific datasheet version for the 744844102 to confirm mechanical dimensions and pin configuration before integration. Ensure that the selected mounting method aligns with the through-hole specifications provided by the manufacturer. Cross-reference the electrical parameters against your system requirements to guarantee compatibility with the intended voltage and current loads.

Selection Notes

Select this component when high current handling capability up to 4.5 A is required alongside significant common mode attenuation. The 1 mH inductance value offers a balance between noise filtering efficiency and physical size constraints. Consider the through-hole package type if mechanical stability and higher thermal dissipation are prioritized over surface area minimization in the design layout.
