74270071

Overview

The Würth Elektronik 74270071 is a cylindrical ferrite cable core from the WE-SAFB series, designed for electromagnetic interference suppression. It features an inner diameter of 1.2 mm and an outer diameter of 3.5 mm, with a height of 3 mm. The component utilizes nickel-zinc ferrite material (7W800) to provide impedance characteristics of 28 Ohms at 25 MHz and 41 Ohms at 100 MHz. It operates within a temperature range of -25°C to +125°C and complies with RoHS and REACH standards.

Feature Summary

• Provides effective electromagnetic interference suppression through high-impedance attenuation in the specified frequency range.
• Features a compact cylindrical design suitable for tight spaces and small-diameter cables.
• Constructed from durable nickel-zinc ferrite material ensuring stable performance across wide temperature variations.

Applications

• Electromagnetic interface noise reduction
• Cable signal integrity enhancement
• General EMI suppression on small wires

Procurement Notes

Verify the specific impedance requirements against application needs, noting values of 28 Ohms at 25 MHz and 41 Ohms at 100 MHz. Confirm that the 1.2 mm inner diameter accommodates the target cable size. Ensure compliance with RoHS and REACH regulations is required for the project. Check current availability as stock levels may vary by region.

Selection Notes

Select this component when space constraints require a small form factor for EMI suppression. The WE-SAFB series is appropriate for applications involving cables with diameters close to 1.2 mm. Consider the operating temperature range of -25°C to +125°C for environmental suitability. Compare impedance curves if specific frequency attenuation profiles are critical for the design.
