Overview
The Würth Elektronik 744821150 is a WE-CMB series common mode power line choke designed for through-hole mounting. It features an inductance of 5 mH with a DC current rating of 1 A and a maximum DC resistance of 220 mOhms. The component operates within a temperature range of -40°C to +125°C and has a voltage rating of 250 V AC. Its vertical package dimensions are 18.00 mm in height, utilizing a 4-pin configuration.
Feature Summary
- Broadband screening capability achieved through low capacitance winding techniques
- Compact design enabling high interference compression relative to physical size
- Optimized for highest possible current handling within small form factors
Applications
- Power electronics noise suppression
- Switch mode supply input filtering
- Common-mode noise reduction in power lines
Procurement Notes
Verify the specific datasheet version for the 744821150 part number to confirm exact electrical tolerances and mechanical drawings. Ensure compatibility with existing PCB footprint requirements, specifically the 4-pin vertical through-hole configuration. Cross-reference operating temperature limits against system thermal profiles to guarantee performance within the specified -40°C to +125°C range during final assembly validation.
Selection Notes
Select this component when broadband EMI suppression is required in space-constrained power applications. The 5 mH inductance and 1 A current rating suit moderate-power line filtering needs. Consider the vertical mounting style for board layout flexibility. Validate that the 220 mOhms DCR aligns with efficiency targets for the specific power stage design before finalizing the bill of materials.
Part Context
This component belongs to the WE-CMB series from Würth Elektronik, specialized as common mode power line chokes. These devices utilize manganese-zinc or nickel-zinc ferrite materials depending on the specific variant within the broader family. The series is engineered to provide effective electromagnetic interference mitigation in compact electronic systems requiring reliable through-hole integration.
Replacement Considerations
Publicly confirmed substitute part numbers for the 744821150 were not identified in the provided documentation. Verify pinout compatibility and inductance values if considering alternative manufacturers. Consult official Wurth Elektronik resources for potential direct replacements within the WE-CMB product line.
