Overview
The Würth Elektronik 7448012002 is a common mode power line choke from the WE-CMBNC series, utilizing nanocrystalline core technology. It features a nominal inductance of 1.6 mH with a tolerance range of -30% to +50%. The component supports a maximum DC current of 2 A and has a maximum DC resistance of 90 mOhms. Designed for through-hole PCB mounting, it operates within a temperature range of -40°C to +125°C. The unit measures 14 mm in length, 7.5 mm in width, and 16 mm in height.
Feature Summary
- Utilizes nanocrystalline core material for effective noise suppression
- Designed as an unshielded power line choke for common mode filtering
- Supports through-hole termination for robust PCB integration
Applications
- Power supply input filtering
- EMI suppression in electronic equipment
- Common mode noise reduction in data lines
Procurement Notes
Verify the specific inductance tolerance requirements against the datasheet specifications before procurement. Confirm that the through-hole footprint dimensions align with the target PCB layout. Ensure the operating environment remains within the specified temperature range of -40°C to +125°C for reliable performance. Cross-reference the manufacturer part number to avoid confusion with similar series components.
Selection Notes
Select this component when high inductance values are required for low-frequency noise attenuation. The nanocrystalline core offers advantages over traditional ferrite materials in specific frequency ranges. Consider the physical size constraints as the through-hole package occupies more board area than surface-mount alternatives. Evaluate the 2 A current rating against the maximum expected load current to prevent saturation.
Part Context
This component belongs to the WE-CMBNC series, which focuses on nanocrystalline common mode chokes. The series provides solutions for applications requiring high inductance and effective EMI suppression. Würth Elektronik designs these components to meet rigorous automotive and industrial standards, ensuring reliability in demanding environments.
Replacement Considerations
Consult official Wurth Elektronik documentation for verified substitute part numbers within the same series or compatible families. Do not assume interchangeability with generic common mode chokes due to differences in core material and magnetic characteristics.
