7427054

Overview

The Würth Elektronik 7427054 is a WE-RIB series multi-aperture EMI suppression core designed for cable noise reduction. It features a NiZn ferrite material composition with a round shape and an inner diameter of 1.8 mm. The component provides an impedance of 94 Ohms at 100 MHz for single-wire applications and 92 Ohms for double-wire configurations. Its external dimensions are 6.4 mm in length, 3.2 mm in width, and 3.5 mm in height. The unit weighs approximately 340 mg and operates within a temperature range of -40°C to +90°C.

Feature Summary

• Multi-aperture design facilitates efficient clamping around cables for effective electromagnetic interference suppression.
• Utilizes NiZn ferrite material optimized for high-frequency noise attenuation in compact spaces.
• Round cross-section geometry ensures uniform magnetic properties around the enclosed conductor.

Applications

• Suppression of common-mode noise on single signal or power cables
• Noise filtering for double-wire data transmission lines
• EMI mitigation in portable electronic devices and consumer electronics

Procurement Notes

Verify the specific impedance requirements against application needs, noting the distinction between single-wire (94 Ohms) and double-wire (92 Ohms) ratings at 100 MHz. Confirm that the 1.8 mm inner diameter accommodates the target cable bundle without excessive force. Ensure compliance with RoHS directives if required by the end product specifications.

Selection Notes

Select this component when space constraints preclude larger toroidal cores but effective high-frequency attenuation is necessary. The 1.8 mm bore size limits usage to smaller gauge wires or tightly bundled thin cables. Consider the operating temperature range up to 90°C for thermal stability in enclosed environments.

Part Context

This part belongs to the WE-RIB family of multi-aperture ferrite cores from Würth Elektronik. These components are engineered specifically for retrofitting onto existing cables to suppress radiated emissions. The design allows for easy installation without cutting or splicing wires, making it suitable for post-assembly EMC improvements.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching impedance values, inner diameter, and material characteristics from alternative manufacturers.
