7427154

Overview

The Würth Elektronik 7427154 is a split-core ferrite clamp from the STAR-RING series, designed for rapid installation on cables. It utilizes 4W620 core material and features a square snap design with an internal diameter of 16 mm. The component measures 35 mm in external length and width, with an external height of 20 mm. It provides an impedance of 71 Ohms at 25 MHz and operates within a temperature range of -25°C to +105°C.

Feature Summary

• Snap-fit mechanism enables quick installation without cable disconnection
• Safety key technology ensures secure electromagnetic compatibility locking
• Split core construction allows retrofitting onto existing wiring

Applications

• General EMI suppression applications
• Safety-related electronic applications

Procurement Notes

Verify the specific impedance value against official datasheets, as distributor listings may vary between 71 Ohms and 130 Ohms at different frequencies. Confirm that the 16 mm inner diameter matches the target cable bundle size. Ensure the 4W620 material composition aligns with required frequency response characteristics for the intended noise spectrum.

Selection Notes

Select this model when a 16 mm aperture is required for larger cable bundles. The STAR-RING series offers distinct mechanical stability compared to standard rings. Verify that the operating temperature range of -25°C to +105°C meets environmental conditions. Consider the snap-fit design for maintenance-friendly installations where cable removal is impractical.
