Fixed Inductors

Fixed inductors are electronic components that have an inductance value that does not normally change over time or with applied voltage. Inductors are a passive electrical component typically composed of insulated copper wire coiled around a central core. These components convert electrical energy into magnetic energy, and are commonly used in radio-frequency circuits, filtering, coupling, and sensing applications.
