7427155

Overview

The Wurth Elektronik 7427155 is a split ferrite core from the STAR-RING Snap series, designed for cable clamping. It features an inner diameter of 27 mm and external dimensions of 55 mm x 48 mm x 20 mm. The core utilizes 4W620 material, providing an impedance of 142 Ohms at 25 MHz and 260 Ohms at 100 MHz. It operates within a temperature range of -25°C to +105°C and weighs 69 g.

Feature Summary

• Snap-fit design allows for rapid installation on cables without disconnection
• Square shape with hinged opening facilitates easy access to conductors
• Constructed from 4W620 ferrite material for effective high-frequency noise suppression

Applications

• Internal and external cable noise suppression
• Small rivet applications
• General EMI filtering on single cables

Procurement Notes

Verify the specific impedance value required for your application, as sources list 142 Ohms at 25 MHz and 260 Ohms at 100 MHz. Confirm the inner diameter matches the target cable size of 27 mm. Ensure compliance with RoHS and REACH standards if mandated by your project specifications before finalizing procurement.

Selection Notes

Select this component when a large aperture ferrite core is needed for thick cables or bundles. The snap-fit mechanism simplifies assembly compared to two-piece cores requiring screws. Consider the 4W620 material properties for the intended frequency range. Verify that the physical dimensions fit within the available space constraints of the enclosure or cable routing path.
