Fixed Inductors

Fixed inductors, also known as fixed coils, are passive electrical components used in various applications to provide electrical current or voltage. They are made from coils of conductive metal wire, such as copper, that are wound around a core such as ferrites.

AIUR-03-1R5M Applications – What They Can Do

Fixed inductors are most often used for filtering signals, transforming signals from AC to DC, increasing current power supply levels, and forming circuits in printed circuit boards. An example of a common application is power protection, where a fixed inductor is used to provide a high-pass filter and helps to prevent electrical surges from entering and damaging a device or system.They are also used for transient suppression, i.e. the protection of analog circuits from high voltage electrical transients. Additionally, in frequency selective circuits, they are used in combination with other components to control the frequency of a signal.

AIUR-03-1R5M Working Principle

The working principle of a fixed inductor is based on the principle of electromagnetic induction. When a current is passed through the coils of the inductor, a magnetic field is created around it, which induces an EMF (electromotive force) in the coils. This EMF creates a counter-electromagnetic field that resists the flow of the current, resulting in a dropped voltage across the coils.In a practical application, a fixed inductor acts as a buffer between an input and output current. When the input current suddenly increases, the inductor provides a delay by storing energy in its magnetic field, allowing the output current to remain the same until the input current stabilizes. This is why a fixed inductor is so important in surge protection applications, where it provides extra protection from electrical spikes.
