Overview

The Würth Elektronik 744861082 is a horizontal common mode power line choke from the WE-TFCH series. It features an inductance of 8.2 mH at 10 kHz and supports a maximum DC current of 500 mA. The component has a maximum DC resistance of 1.3 Ohms. Designed for through-hole PCB mounting, it operates within a temperature range of -40°C to +125°C. The unit utilizes ferrite core material and is unshielded.

Feature Summary

Horizontal form factor design for compact PCB integration
Ferrite core construction for effective noise suppression
Through-hole termination for robust mechanical stability

Applications

Mains filters
Compact switched-mode power supplies
Lighting systems
White goods applications

Procurement Notes

Verify the specific datasheet revision when ordering, as manufacturing updates may occur. Confirm that the horizontal orientation matches your board layout constraints. Ensure the 500 mA current rating meets your circuit requirements. Check for any RoHS compliance documentation if required by your procurement policy. Validate pin spacing against your PCB footprint specifications before finalizing the purchase.

Selection Notes

Select this component for applications requiring horizontal mounting to save vertical space. The 8.2 mH inductance provides significant common mode noise attenuation. The 1.3 Ohm DCR minimizes voltage drop in low-current circuits. Consider the -40°C to +125°C operating range for industrial environments. Compare with other WE-TFCH variants if different current or inductance values are needed.

Part Context

This part belongs to the WE-TFCH series of common mode chokes. The series offers various inductance and current ratings. Horizontal designs facilitate dense PCB layouts. Ferrite cores provide high permeability for EMI suppression. The product line targets power supply and consumer electronics markets.
