WebIn this use, the bead is a simple form of a balun. Ferrite beads are one of the simplest and least expensive types of interference filters to install on preexisting electronic cabling. For a simple ferrite ring, the wire is simply wrapped around the core through the center, typically five or seven times. WebImpedance transformers in the Palomar Engineers’ product line have input/output ratios either less than 1:1 (like 50 ohm input to 25 ohm output) or greater than 1:1 (like 50 ohm input to 200 ohm output). Feed line chokes and impedance transformers can be configured as unbalanced or balanced output each having identical ferrite transformers.
