Multicomp Pro MP 33RI Series Ferrite Core, Cylindrical, 120 Ohm, 12g

The Multicomp Pro MP 33RI Series Ferrite Core is a specialised cylindrical component designed to improve the performance and reliability of sensitive electronic equipment. This core functions as a toroidal ferrite suppressor, effectively attenuating and suppressing high-frequency electrical noise in signal and data cables. By placing this core around a cable, it creates an impedance to unwanted radio frequency interference (RFI) and electromagnetic interference (EMI), which can cause data corruption, signal degradation, and erratic behaviour in connected devices.

This specific model offers an impedance of 120 Ohms and is optimised for a frequency range of 25MHz to 100MHz, making it ideal for cleaning up noise in various digital and analogue circuits. Its robust cylindrical construction ensures durability and easy installation, simply by clamping it around the target cable. The ferrite material provides excellent attenuation characteristics without affecting the desired signal, preserving the integrity of your data transmission and audio/video quality.

Key Applications

This ferrite core is essential for use in computers and computer peripherals, where it can reduce interference from monitors, printers, and external drives on USB, HDMI, or network cables. In audio setups, it helps eliminate hums and buzzes, leading to cleaner sound output from speakers, microphones, and amplifiers. It is also highly effective for any home entertainment system, networking equipment, or diagnostic instrumentation where signal clarity is paramount.
