7427056

Overview

The Würth Elektronik 7427056 is a round ferrite cable core from the WE-Rib series, designed for electromagnetic interference suppression. It features an inner diameter of 4 mm and external dimensions of 14 mm length, 13.5 mm width, and 7.5 mm height. The component utilizes NiZn core material and provides an impedance of 260 Ohms at 100 MHz for single-wire applications, or 182 Ohms for double-wire configurations. It operates within a temperature range of -40°C to +90°C and is supplied in bulk packaging.

Feature Summary

• Round geometry facilitates easy installation around cables
• NiZn material composition supports high-frequency attenuation
• Dual impedance ratings accommodate single and double wire setups

Applications

• EMI suppression on single wires
• EMI suppression on double wires
• General signal line filtering

Procurement Notes

Verify the specific impedance requirement against the application's wiring configuration, as the datasheet distinguishes between single-wire (260 Ohms) and double-wire (182 Ohms) performance at 100 MHz. Confirm that the 4 mm inner diameter accommodates the target cable bundle without mechanical stress. Ensure compliance with the specified operating temperature range of -40°C to +90°C for the intended environment.

Selection Notes

Select this component when a compact, round ferrite core is required for small-diameter cables up to 4 mm. The WE-Rib series offers a balance of size and impedance for general-purpose EMI reduction. Consider the NiZn material properties for frequency ranges where this material excels. Compare against split-core options if frequent cable access is necessary, though this model is a solid ring design.

Part Context

This part belongs to the WE-Rib family of ferrite cores from Würth Elektronik. These components are engineered for broadband noise suppression in electronic assemblies. The round shape differentiates it from rectangular or split-core alternatives, offering uniform magnetic path characteristics around the conductor.
