Overview

The Würth Elektronik 7448040707 is a WE-CMBNC Type L Nancrystl common mode choke designed for power line filtering. It features a nominal inductance of 7 mH at a test frequency of 10 kHz with a tolerance range of -30% to +50%. The component supports a maximum DC current of 7 A and exhibits a maximum DC resistance of 20 mOhms. Constructed for through-hole PCB mounting, it operates within a temperature range of -40°C to +125°C. The unshielded unit measures 28 mm in length, 19 mm in width, and 32 mm in height, weighing approximately 17.1 g.

Feature Summary

Utilizes Nancrystl core technology for high-performance common mode noise suppression
Engineered for robust power line applications requiring high current handling
Designed for reliable operation across extended industrial temperature ranges

Applications

Power supply input filtering
Industrial equipment EMI suppression
Unshielded power line noise reduction

Procurement Notes

Verify the specific manufacturer part number against official Wurth Elektronik documentation to ensure authenticity. Confirm that the required inductance tolerance (-30%, +50%) aligns with circuit design specifications. Ensure the through-hole mounting style and physical dimensions fit the target PCB layout constraints before finalizing procurement decisions.

Selection Notes

Select this component when high current capacity up to 7 A is required alongside significant common mode attenuation at low frequencies. The unshielded construction necessitates careful PCB placement to avoid interference with nearby sensitive traces. Verify that the thermal environment remains within the specified -40°C to +125°C operational limits for long-term reliability.

Part Context

This component belongs to the WE-CMBNC series, specifically the Type L variant utilizing Nancrystl material. This series targets power line chokes where high saturation current and stable inductance are critical. The part represents a specialized solution for electromagnetic compatibility in demanding electronic environments.
