7427606

Overview

The Würth Elektronik 7427606 is an axial ferrite bead from the WE-WAFB series, designed for electromagnetic interference suppression. It features a 130 Ohm impedance at a test frequency of 100 MHz and supports a maximum DC current of 3 A. The component has a low maximum DC resistance of 5 mOhms and a tolerance of 25%. Its physical dimensions are 9 mm in length with a diameter of 3.5 mm. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides effective high-frequency noise attenuation through high impedance characteristics
• Axial leaded construction facilitates easy integration into existing wiring harnesses
• Low DC resistance minimizes power loss during normal operation
• Capable of handling high continuous DC currents without saturation

Applications

• Electromagnetic compatibility filtering in electronic circuits
• Noise suppression on data and power lines
• Integration into cable assemblies for signal integrity enhancement

Procurement Notes

Verify the specific impedance value and current rating against the official datasheet before procurement. Confirm that the axial package dimensions fit the intended mechanical constraints. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number to avoid counterfeit components.

Selection Notes

Select this component when axial mounting is preferred over surface mount options. Choose based on the required 130 Ohm impedance at 100 MHz for the target noise spectrum. Ensure the circuit current does not exceed the 3 A maximum rating. Consider the low DC resistance for applications where voltage drop must be minimized.

Part Context
