Wurth Elektronik Openable Snap Ferrite Ring STAR-RING Series, Diameter 27 mm, Impedance 54Ω at 25 MHz, 112Ω at 100 7427155S

Wurth Elektronik 7427155S openable snap ferrite ring from the STAR-RING Series features a 27 mm aperture diameter designed to suppress electromagnetic interference (EMI) on single conductors or cable bundles. Constructed from 4W620 ferrite material, it delivers 54Ω impedance at 25 MHz and 112Ω impedance at 100 MHz to provide effective noise attenuation across mid-to-high frequency bands.

The ferrite ring uses an openable snap-on structure enabling simple, tool-free retrofitting to existing cabling installations without the need for disconnection. Its single aperture design supports one conductor or grouped cables sized to the 27 mm internal diameter, allowing targeted EMI suppression where needed.

External dimensions measuring 55 mm width, 44 mm height, and 20 mm depth ensure easy integration within assemblies without interference. It is suitable for both general and safety-relevant electrical and electronic applications, including power and signal line noise reduction.

Compliant with RoHS and REACH regulations, this component meets environmental and chemical substance restrictions, supporting safe and sustainable manufacturing practices. Produced in Germany under strict manufacturing protocols, it provides high reliability and performance for industrial, electronic, and safety equipment manufacturers.

Constructed from 4W620 ferrite material for efficient EMI noise attenuation. 54Ω impedance at 25 MHz and 112Ω at 100 MHz targeting mid and high-frequency EMI. Snap-on openable design facilitates easy installation around cables.

Single aperture for individual cable choking or bundles up to 27 mm diameter. Compact dimensions (55x44x20 mm) suited for embedded applications. RoHS and REACH compliance ensures regulatory adherence. Made in Germany following quality and safety standards.

This ferrite ring is ideal for EMI suppression in electronic assemblies, retrofit applications on existing cabling, and safety-relevant circuits where electromagnetic noise must be controlled.
