Inductors, Air Core Inductors and Baluns
These passive electrical components are designed to store energy in the form of a magnetic field, and we define them by their inductance, measured in Henries (H). Inductors take the form of a coil of wire wound around a magnetic core.
Inductors filter out high-frequency noise and minimize changes in current in power supplies, radio frequency (RF) circuits and audio circuits. Their resistance to current change makes them useful for designing filters, tuning circuits, and when paired with capacitors, smoothing out signals.
Sometimes referred to as an air core coil, an air core inductor is an insulated coil with nothing but air and windings in its core. These are typically deployed in RF circuits because of their low-loss characteristics.
Advantages of Air Core Inductors
●Absence of Nonlinearities: The inductance of an air core inductor doesn’t change in response to applied current or voltage because air doesn’t exhibit nonlinear magnetic properties.
●Absence of Saturation: Unlike ferromagnetic materials (e.g., iron, nickel, cobalt), air does not saturate. This means the inductance of an air-core inductor does not decrease significantly at high current levels.
●High Q Factor: Because air core inductors have no solid core material, there are no energy losses due to hysteresis or eddy currents, which makes their Q factor (a measure of efficiency) high.
These electrical transformers are designed to maintain balance. Baluns can convert between a balanced signal and an unbalanced signal. A balanced signal is one where there are equal voltages on two lines with opposite phases; an unbalanced signal refers to a single voltage on one line. A common example is radio and television antenna systems, where baluns help connect a balanced antenna to an unbalanced feed line (e.g., coaxial cable).
Baluns take many forms. For example, some baluns feature an impedance matching network, so they can match the impedance between the source and the load. This application is important in RF, where impedance mismatches can cause reflections and reduce system efficiency.

The Inductor Coil Manufacturer Briefly Describes the Performance Indicators of the Inductor Coil for You
The inductance of an inductor coil is a key performance index, determined by factors such as the number of turns, winding method, and presence of a magnetic core. The basic unit of inductance is Henry (H), with common units including millihenry (mH) and microhenry (μH). Inductance coils also exhibit inductive reactance and a quality factor (Q) related to their efficiency. Distributed capacitance and rated current are also important considerations.
