7427057

Overview

The Würth Elektronik part number 7427057 is a multi-aperture ferrite cable core belonging to the WE-RIB series. It is designed for electromagnetic interference suppression on single and double wire configurations. The component utilizes NiZn material and features a round shape with an internal diameter of 4 mm. External dimensions are 13.5 mm in length, 7 mm in width, and 7.5 mm in height. Impedance values are specified as 97 Ohms at 100 MHz for single wire and 104 Ohms at 100 MHz for double wire applications. The operating temperature range spans from -40 °C to +90 °C.

Feature Summary

• Multi-aperture design for enhanced EMI suppression
• Suitable for single and double wire configurations
• NiZn ferrite material construction

Applications

• Single wire EMI suppression
• Double wire EMI suppression
• General purpose cable filtering

Procurement Notes

Verify the specific impedance requirements against the datasheet specifications for single and double wire setups. Confirm that the internal diameter of 4 mm accommodates the target cable bundle. Ensure the operating temperature range of -40 °C to +90 °C meets the environmental conditions of the intended application. Cross-reference the WE-RIB series documentation for accurate mechanical fitment.

Selection Notes

Select this component when multi-aperture performance is required for compact cable assemblies. The 4 mm inner diameter limits suitability to smaller gauge wires or bundled cables fitting within that constraint. Consider the NiZn material properties for high-frequency noise attenuation. Evaluate the physical dimensions of 13.5 x 7 x 7.5 mm for spatial constraints in the installation area.

Part Context

This component is part of the WE-RIB series from Würth Elektronik, which focuses on ferrite cable cores for electromagnetic interference suppression. The series offers various aperture sizes and impedance characteristics to suit different cable diameters and frequency requirements. The multi-aperture design distinguishes it from standard single-hole cores by providing increased attenuation per unit length.
