Wurth Elektronik Ferrite Ring 28.5 mm Height, 8.2 mm ID, 14.2 mm OD Ferrite Core, 25 - 100 MHz, 3 W 800 Material 74270081

The Wurth Elektronik 74270081 Ferrite Ring is a high-quality passive EMI suppression component engineered to reduce electromagnetic interference in signal and power cables. This ring is crafted from 3 W 800 ferrite material, offering an optimized solution for blocking high-frequency noise without disturbing the transmission of data signals.

With a height of 28.5 mm, an internal diameter of 8.2 mm, and an outer diameter of 14.2 mm, this ferrite ring is designed to fit a wide range of cable sizes encountered in industrial and commercial electronic systems. The part operates effectively across the 25 MHz to 100 MHz frequency range, making it suitable for attenuation of unwanted signals in general electronics, power distribution, and sensitive electronic assemblies.

The 74270081 model is easy to install, typically fitted over cables and can be secured using heat shrink sleeving for a robust assembly. Its increased ferrite content leads to improved attenuation properties compared to standard ferrite rings and its performance can be further enhanced by threading the cable through the ring multiple times.

Common application scenarios include use with coaxial cables, twisted-pair lines, multicore cables, and other wiring where EMI needs to be controlled. The product is suitable for use in laboratory, industrial, commercial, and electronic manufacturing environments where signal clarity and compliance with EMC standards are critical. Compliant with RoHS requirements, it enables designers to meet environmental and industrial safety standards.

This ferrite ring provides a reliable, maintenance-free EMI solution for circuit protection and signal integrity. Explore more EMI filters, Ferrite Rings, and advanced passive components from Wurth Elektronik and related electronics categories at EnvMart.
