N89AB in catalogue
A range of clip-on ferrite rings designed to cure electromagnetic & radio frequency interference at source. Always choose an internal diameter close to that of the cable or wind through several times. Always put ferrites at the noisy end of the cable.
from £2.29
QT26D
One of the easiest ways to cure RF interference is using these popular ferrite rings. Simply wind a few turns of any hi-fi lead, TV aerial coax or mains lead around the ring to prevent interfering radio signals travelling into the equipment.

RG21X in catalogue
• Used for radio interference suppression of small electric motors and domestic appliances • The delta filter is connected between the live, neutral and earth terminals to reduce RFI • Best results require installation close to the source of the interference • Encapsulated thermoplastic, sealed with polyurethane resin • 250V AC rated • UK manufactured
only £2.99
CP76H in catalogue
These devices are simply connected directly across the power supply. They have a very high resistance up to the Vm voltage shown in the table below and therefore usually may be ignored, but the moment a transient spike appears on the supply line which exceeds Vm, the impedance of the device drops immediately to a very low level while it dissipates the unwanted energy. For example, Suppressor 275Vac can be connected directly across the UK mains supply. Please note that the use of AC in the d

WH37S in catalogue
A range of RF chokes having a triple barrier against moisture, and high termination strength and reliability. Colour code (as resistors) gives value in µH.
from £0.69
