7448040515

Overview

The Würth Elektronik 7448040515 is a two-line common mode choke from the WE-CMBNC series, designed for through-hole mounting. It features an inductance of 15 mH at 10 kHz and supports a maximum DC current of 5 A. The component has a maximum DC resistance of 40 mOhms per line. It operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides common mode noise suppression for dual-line applications
• Utilizes through-hole termination for PCB integration
• Constructed with NiZn core material for stable performance

Applications

• Power supply input filtering
• Data line noise suppression
• EMI reduction in industrial equipment

Procurement Notes

Verify the specific package type and lead configuration against the official datasheet before ordering. Confirm that the 15 mH inductance value and 5 A current rating align with the circuit requirements. Ensure the through-hole mounting style matches the target PCB design constraints.

Selection Notes

Select this component when dual-line common mode filtering is required with high current handling capabilities. The 15 mH inductance offers significant attenuation for common mode signals. Consider the through-hole form factor if surface space is limited or mechanical robustness is prioritized over miniaturization.

Part Context

This part belongs to the WE-CMBNC series of common mode chokes manufactured by Würth Elektronik. The series focuses on providing reliable noise suppression solutions for power and signal lines. Components in this family are characterized by their robust construction and consistent electrical performance across varying environmental conditions.

Replacement Considerations

Check for compatible parts within the WE-CMBNC series that match the 15 mH inductance and 5 A current specifications. Verify pin compatibility and physical dimensions for direct substitution. Consult manufacturer cross-reference lists for verified alternatives.
