Balun

A balun (from "balanced to unbalanced", originally, but now derived from "balancing unit") is an electrical device that allows balanced and unbalanced lines to be interfaced without disturbing the impedance arrangement of either line.

See Ferrite bead and Balun

Braid-breaker

A braid-breaker is a filter that prevents television interference (TVI).

See Ferrite bead and Braid-breaker

Cable tie

A cable tie (also known as a hose tie, tie wrap, wire tie, zap-straps, or zip tie) is a type of fastener for holding items together, primarily electrical cables and wires.

See Ferrite bead and Cable tie

Choke (electronics)

In electronics, a choke is an inductor used to block higher-frequency alternating currents (AC) while passing direct current (DC) and lower-frequency ACs in a circuit. Ferrite bead and choke (electronics) are Wireless tuning and filtering.

See Ferrite bead and Choke (electronics)

Coaxial cable

Coaxial cable, or coax (pronounced), is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric (insulating material); many coaxial cables also have a protective outer sheath or jacket.

See Ferrite bead and Coaxial cable

Decoupling (electronics)

In electronics, decoupling is the prevention of undesired electrical energy transfer (coupling) between subsystems.

See Ferrite bead and Decoupling (electronics)

Electrical impedance

In electrical engineering, impedance is the opposition to alternating current presented by the combined effect of resistance and reactance in a circuit.

See Ferrite bead and Electrical impedance

Electrical reactance

In electrical circuits, reactance is the opposition presented to alternating current by inductance and capacitance.

See Ferrite bead and Electrical reactance

Electrical resistance and conductance

The electrical resistance of an object is a measure of its opposition to the flow of electric current.

See Ferrite bead and Electrical resistance and conductance

Electromagnetic interference

Electromagnetic interference (EMI), also called radio-frequency interference (RFI) when in the radio frequency spectrum, is a disturbance generated by an external source that affects an electrical circuit by electromagnetic induction, electrostatic coupling, or conduction.

Ferrite (magnet)

A ferrite is one of a family of iron oxide-containing magnetic ceramic materials. Ferrite bead and ferrite (magnet) are ferrites.

Fuse (electrical)

In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit.

HowStuffWorks

HowStuffWorks is an American commercial infotainment website founded by professor and author Marshall Brain, to provide its target audience an insight into the way many things work.

Inductor

An inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it.

See Ferrite bead and Inductor

InfoSpace

Infospace, Inc. was an American company that offered private label search engine, online directory, and provider of metadata feeds.

Integrated circuit

An integrated circuit (IC), also known as a microchip, computer chip, or simply chip, is a small electronic device made up of multiple interconnected electronic components such as transistors, resistors, and capacitors.

See Ferrite bead and Integrated circuit

Low-pass filter

A low-pass filter is a filter that passes signals with a frequency lower than a selected cutoff frequency and attenuates signals with frequencies higher than the cutoff frequency.

See Ferrite bead and Low-pass filter

Magnetic core

A magnetic core is a piece of magnetic material with a high magnetic permeability used to confine and guide magnetic fields in electrical, electromechanical and magnetic devices such as electromagnets, transformers, electric motors, generators, inductors, loudspeakers, magnetic recording heads, and magnetic assemblies. Ferrite bead and magnetic core are electromagnetic radiation.

Noise (electronics)

In electronics, noise is an unwanted disturbance in an electrical signal.

Parasitic oscillation

Parasitic oscillation is an undesirable electronic oscillation (cyclic variation in output voltage or current) in an electronic or digital device.

Passivity (engineering)

Passivity is a property of engineering systems, most commonly encountered in analog electronics and control systems.

See Ferrite bead and Passivity (engineering)

Radio frequency

Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around to around.

Regulatory compliance

In general, compliance means conforming to a rule, such as a specification, policy, standard or law.

Unintentional radiator

In United States regulatory law, an unintentional radiator is any device that is designed to use radio frequency electrical signals within itself, or sends radio frequency signals over conducting cabling to other equipment, but is not intended to radiate radio frequency energy.
