DX Engineering Ferrite - HF Large Toroid Pack of four mix-31 toroids is destined to be one of our most popular kits. These toroids are used extensively in electronics. They are often used for baluns, common mode chokes and a myriad of RF suppression tasks. Found in RF equipment from line isolators to amplifiers, these toroids are well suited for tasks in the HF range. With proper winding, they can provide very effective RF suppression, RFI prevention and common-mode noise reduction on feedlines, AC or DC power wires, audio, switching and keying cables. Use them on virtually any cable connected to a transceiver including speaker, CW keyer and USB and serial cables. DX Engineering HF Large Toroids are ready for your RFI prevention or electronics project.

DX Engineering Ferrite toroids are color coded so you can determine their mix and frequency coverage years after the packaging is gone.
