Part number:



As a leading manufacturer of miniature air coils for microelectronics applications, Microwave Components, Inc. offers a comprehensive line of standard components as well as components that are custom engineered to meet the widest possible range of inductance requirements.

The entire line is available in a variety of wire materials that includes copper, gold, silver, and specific alloys. Within this selection, configurations include spaced coils, coated and tinned coils, and alloy metal coils that offer resistive inductance. All of these miniature air coils afford multi-octave performance, high "Q", and low loss. Other features provide controlled self-resonance and mechanical soundness for in-circuit handling. Applications include all popular circuits such as mixers, filters, modulators, multipliers, oscillators, and switches.


Chip inductors are passive two-terminal electrical component that stores energy in its magnetic field. For comparison, a capacitor stores energy in an electric field, and a resistor does not store energy but rather dissipates energy as heat.

Any conductor has inductance. An inductor is typically made of a wire or other conductor wound into a coil, to increase the magnetic field.

When the current flowing through a chip inductor changes, a time-varying magnetic field is created inside the coil, and a voltage is induced, according to Faraday’s law of electromagnetic induction, which by Lenz's law opposes the change in current that created it. Chip inductors are one of the basic components used in electronics where current and voltage change with time, due to the ability of inductors to delay and reshape alternating currents.
