Overview
The Würth Elektronik 7448011305 is a common mode power line choke from the WE-CMBNC series, utilizing nanocrystalline core technology. It features a single-channel configuration with an inductance of 5 mH at a test frequency of 10 kHz. The component supports a maximum DC current of 1.3 A and has a maximum DC resistance of 0.2 Ohms. Designed for through-hole PCB mounting, it operates within a temperature range of -40°C to +125°C. The unshielded unit measures 14 mm in length, 7.5 mm in width, and 16 mm in height.
Feature Summary
- Utilizes nanocrystalline material for high common mode impedance performance
- Designed for effective noise suppression on power lines
- Supports through-hole mounting for robust PCB integration
Applications
- Power supply input filtering
- EMI suppression in electronic equipment
- Noise reduction in industrial control systems
Procurement Notes
Verify the manufacturer part number 7448011305 against official Wurth Elektronik documentation to ensure authenticity. Confirm that the received components match the specified electrical parameters, including 5 mH inductance and 1.3 A current rating. Check for physical integrity and correct through-hole pin configuration before assembly. Ensure compliance with RoHS directives as indicated in the product specifications.
Selection Notes
Select this component when nanocrystalline cores offer superior low-frequency attenuation compared to ferrite alternatives. The 5 mH inductance and 1.3 A rating suit applications requiring moderate current handling with significant common mode noise rejection. Consider the through-hole package if mechanical stress resistance or higher thermal dissipation is required over surface-mount options.
Part Context
This component belongs to the WE-CMBNC series, which specializes in common mode chokes using nanocrystalline materials. This series is engineered for power line applications where high impedance across a broad frequency range is critical. The nanocrystalline structure provides distinct advantages in saturation characteristics and permeability compared to traditional ferrite cores.
Replacement Considerations
Cross-reference with other WE-CMBNC variants for different current or inductance requirements. Verify pin compatibility and physical dimensions when substituting with similar common mode chokes from other manufacturers.
