74276032

Overview

The Würth Elektronik 74276032 is a WE-WAFB series sleeve choke designed for axial through-hole mounting. It features a single-channel configuration with an impedance of 83 Ohms at 100 MHz and a maximum DC current rating of 6 A. The component exhibits a maximum DC resistance of 5 mOhms and an inductance of 737 nH with a 25% tolerance. Operating within a temperature range of -55°C to +125°C, it measures 5 mm in length and 3.5 mm in diameter, with leads of 0.65 mm diameter.

Feature Summary

• Provides common mode noise suppression via axial ferrite bead construction
• Supports high current handling up to 6 A with low DC resistance
• Designed for reliable operation across extended industrial temperature ranges

Applications

• Electromagnetic interference filtering in power supply lines
• Noise suppression in automotive electronic circuits
• Signal integrity protection in general purpose PCB assemblies

Procurement Notes

Verify the specific impedance value and current rating against the official datasheet before integration. Confirm that the axial lead dimensions match the target PCB footprint requirements. Ensure compliance with RoHS3 standards if required by the end product specifications. Check for any recent production change notices affecting material composition or performance characteristics.

Selection Notes

Select this component when high current capacity and compact axial form factor are required for through-hole implementation. The 83 Ohm impedance at 100 MHz targets specific high-frequency noise profiles. Consider the 5 mOhm DC resistance for minimal voltage drop in high-current paths. Evaluate thermal management needs given the 6 A rating and operating temperature limits.
