Overview
The Würth Elektronik 744834433 is a horizontal common mode power line choke from the WE-CMBH series. It features an inductance of 3.3 mH at 10 kHz and supports a DC current rating of 5 A with a maximum DC resistance of 37 mΩ. Designed for through-hole mounting, this component operates within a temperature range of -40°C to +125°C. The unit utilizes a toroidal core structure and includes a lead spacing of 27.5 mm for reliable PCB integration.
Feature Summary
- Horizontal common mode filtering configuration
- Toroidal core construction for high efficiency
- Through-hole mounting for mechanical stability
Applications
- AC power line input filtering
- EMI suppression in industrial equipment
- Power supply noise reduction
Procurement Notes
Verify the specific datasheet version for the 744834433 part number to confirm exact physical dimensions and pinout compatibility before finalizing design integration. Ensure that the selected supplier provides documentation confirming compliance with RoHS3 standards and REACH regulations as specified by the manufacturer for environmental safety.
Selection Notes
Select this component when horizontal mounting space constraints require a low-profile common mode choke. The 5 A current rating and 3.3 mH inductance make it suitable for general AC mains filtering applications where significant common mode noise attenuation is required at lower frequencies.
Part Context
This component belongs to the WE-CMBH series of common mode chokes manufactured by Würth Elektronik. The series is characterized by its horizontal form factor and toroidal geometry, designed to provide effective electromagnetic interference suppression in power line applications while maintaining a compact footprint relative to vertical alternatives.
Replacement Considerations
Consult official substitution lists for equivalent WE-CMBH variants or other manufacturers' horizontal common mode chokes with matching 3.3 mH inductance and 5 A current ratings. Verify that any substitute maintains the same 27.5 mm lead spacing and through-hole package compatibility.
