74270090

Overview

The Würth Elektronik part number 74270090 is an axial ferrite bead belonging to the WE-ABF series. It features a solid ferrite core with a 13 mm inner diameter and provides an impedance of 250 Ohms at 100 MHz. The component is designed for electromagnetic interference suppression in electronic circuits, utilizing nickel-zinc ferrite material suitable for frequencies between 25 MHz and 100 MHz.

Feature Summary

• Provides 250 Ohms impedance at 100 MHz for effective high-frequency noise attenuation
• Utilizes nickel-zinc ferrite material optimized for EMI suppression applications
• Features a solid axial design with a 13 mm inner diameter for cable mounting

Applications

• Electromagnetic interference suppression on cables
• Common mode choke applications in electronic interfaces
• Noise filtering in general electronic equipment

Procurement Notes

Verify the specific impedance value and frequency rating against the official Wurth Elektronik datasheet before integration. Confirm that the 13 mm inner diameter accommodates the target cable or wire gauge. Ensure compliance with RoHS and REACH standards required by the end application. Cross-reference the part number to distinguish it from similar WE-ABF variants with different dimensions or impedance characteristics.

Selection Notes

Select this component when a 250 Ohm impedance at 100 MHz is required for EMI mitigation. The 13 mm bore size dictates the maximum cable diameter that can pass through the core. Consider the operating temperature range and current carrying capacity if the bead carries signal or power currents. Compare with other WE-ABF models if different impedance levels or physical sizes are needed for the specific PCB or cable assembly constraints.

Part Context

This component is part of the Würth Elektronik WE-ABF series of axial ferrite beads. These components are engineered for suppressing electromagnetic interference in various electronic applications. The series offers multiple impedance values and physical sizes to suit different cable diameters and frequency requirements, providing flexible solutions for EMC compliance in consumer and industrial electronics.

Replacement Considerations

Check for direct substitutes within the WE-ABF series that match the 250 Ohm impedance and 13 mm inner diameter. Verify that any alternative part maintains the same nickel-zinc ferrite composition and frequency response characteristics to ensure equivalent performance in the existing circuit design.
