7427154S

Overview

The Würth Elektronik 7427154S is a split ferrite clamp core from the STAR-RING series, designed for rapid installation on cables. It utilizes 4W620 material to provide effective EMI suppression. Key electrical parameters include an impedance of 71 Ω at 25 MHz and 132 Ω at 100 MHz. The component features a 16 mm inner diameter to accommodate various cable sizes. Physical dimensions are 43 mm in width, 32 mm in height, and 20 mm in depth. It operates within a temperature range of -25°C to +105°C.

Feature Summary

• Hinged snap design allows for quick installation onto existing cables without disconnection.
• Utilizes 4W620 ferrite material optimized for broadband electromagnetic interference attenuation.
• Square cross-section geometry provides stable clamping force around cylindrical conductors.

Applications

• Suppression of common-mode noise on data communication lines
• EMI reduction in industrial control wiring harnesses
• Noise filtering for AC power tool cords

Procurement Notes

Verify the specific impedance values (71Ω @ 25MHz, 132Ω @ 100MHz) against your system requirements. Confirm the 16mm aperture fits the target cable bundle diameter. Ensure the operating temperature range of -25°C to +105°C meets environmental conditions. Check RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this model when non-invasive installation is required for cable assemblies. The 16mm bore size suits medium-diameter cables. Choose based on the required attenuation profile at 25MHz and 100MHz. The hinged mechanism eliminates the need for cable removal during retrofitting or maintenance procedures.

Part Context

This component belongs to the STAR-RING series of clamp-on ferrites from Würth Elektronik. These cores are engineered for easy deployment on pre-assembled cables. The series offers various impedance profiles and aperture sizes to address different frequency ranges and cable diameters in electronic equipment.

Replacement Considerations

Direct substitutes must match the 16mm aperture, 4W620 material composition, and similar impedance characteristics at 25MHz and 100MHz. Verify physical dimensions (43x32x20mm) for enclosure compatibility. Hinged designs are functionally equivalent to split cores with locking mechanisms.
