Product Description

Wurth Elektronik 7427155S is an openable snap ferrite ring designed for electromagnetic interference (EMI) reduction on cables within electronic and electrical assemblies. The Ferrite Ring has a precise aperture diameter of 27 mm, enabling installation onto existing conductors or grouped cables without circuit disconnection via its innovative snap-on design.

Made from specialized 4W620 ferrite material, the component offers impedance values of 54 ohms at 25 MHz and a higher 112 ohms at 100 MHz, achieving effective mid-to-high frequency EMI suppression. Its single aperture form factor facilitates choking individual cables, making it highly versatile for various general and safety-relevant applications.

The external dimensions are 55 mm width, 44 mm height, and 20 mm depth, providing a compact housing for integration within cable harnesses or assemblies. Compliance with RoHS and REACH regulations certifies reduced hazardous substances, ensuring a safer environmental impact.

Typical use cases include suppression of cable-borne noise in industrial equipment, electronic signals, power lines, and retrofit scenarios where tool-free installation is critical. Its reliable performance makes it suitable for manufacturing, laboratory, HVAC, telecom, and other commercial electrical applications requiring EMI mitigation.

High impedance at specified frequencies for effective EMI attenuation. Openable snap geometry for easy and quick retrofit on existing cables. Constructed from RoHS and REACH-compliant 4W620 ferrite material. Designed for safety-relevant electronics and general EMI suppression.

Compact and space-efficient external dimensions facilitate mounting. Single aperture allows one cable or grouped conductor routing. Manufactured in Germany with quality assurance. Ideal for use in electronic assemblies, power and signal line noise reduction.
