Procurement Notes
Verify the specific part number 7448030509 against official Würth Elektronik datasheets to confirm technical specifications. Ensure compatibility with required current ratings and inductance values for the target application. Cross-reference manufacturer documentation for accurate RoHS compliance status and environmental operating conditions before procurement.
Selection Notes
Select this component when a 9 mH inductance at 10 kHz is required for common mode noise reduction. Consider the 5 A current rating and 32 mOhm DCR for power loss calculations. Evaluate the through-hole package size of 22.00 mm x 13.50 mm against available PCB space constraints. Confirm suitability for the intended voltage rating of 250 V AC.
Part Context
This component belongs to the WE-CMBNC series of common mode chokes manufactured by Würth Elektronik. The series employs Nancrystl technology to provide reliable noise filtering solutions. These components are engineered for use in general electronic equipment where effective electromagnetic interference suppression is necessary for stable operation.
Replacement Considerations
Consult official Würth Elektronik substitution guides for verified alternative part numbers within the WE-CMBNC series or other compatible families. Do not assume interchangeability based solely on similar electrical parameters without manufacturer confirmation.
