7448041801

Overview

The Würth Elektronik 7448041801 is a common mode filter choke belonging to the WE-CMBNC series. It features a Type L Nancrystl core and is designed for through-hole PCB mounting. The component provides a nominal inductance of 1500 µH (1.5 mH) with a tolerance range of -30% to +50%. It supports a maximum DC current of 18 A and has a maximum DC resistance of 3.2 Ω. The device operates within a temperature range of -40°C to +125°C and holds AEC-Q200 automotive qualification.

Feature Summary

• Utilizes Nancrystl core technology for high-performance common mode filtering
• Automotive qualified under AEC-Q200 standards
• Designed for through-hole PCB mounting applications

Applications

• Power line filtering in automotive electronics
• Common mode noise suppression in industrial equipment
• EMI reduction in power supply circuits

Procurement Notes

Verify the specific datasheet version and manufacturing date code upon order confirmation. Ensure that the required inductance tolerance (-30% to +50%) aligns with the circuit design specifications. Confirm that the 18 A current rating and 3.2 Ω DC resistance are suitable for the target application's thermal and electrical constraints before finalizing procurement.

Selection Notes

Select this component when a high-current common mode choke with automotive reliability is required. The 1500 µH inductance value is suitable for low-frequency noise suppression at 10 kHz. Consider the through-hole package style if surface mount options are not feasible for the mechanical assembly requirements.
