IR02BH1R0J Fixed Inductor Application Field and Working Principle

Fixed inductors, or chokes, are electrical components used to store energy in the form of a magnetic field. As part of a circuitry, fixed inductors provide the necessary inductance, allowing for enhanced frequency regulation and transient protection. The IR02BH1R0J is a type of fixed inductor manufactured by Mouser Electronics®, an international distributor of electronic components. IR02BH1R0J is used in various applications and works on the principle of electromagnetic induction.

Application Field

The IR02BH1R0J, or ferrite-bead inductor, is an outstandingly versatile component with a variety of uses across a wide range of sectors and applications. It is typically used in a variety of converters, such as DC-to-DC converters, switchmode DC-to-AC inverters, and AC adaptors. In addition, this inductor is used in power regulators and battery-charger circuits. It is also utilized in mobile and automotive electronics, and in overvoltage protection systems, and can be used to control and shape electrical noise.

Working Principle

The IR02BH1R0J inductor is an electromagnetic device which works by creating a magnetic field in order to store energy. This process of energy storage is based on the principle of electromagnetic induction, developed by the physicist Michael Faraday and respectfully coined "Faraday\'s Law". This law states that the magnitude of induced electromotive force within the inductor is proportional to the rate of change of the magnetic flux through the core. In the most basic terms, this means that, when current is applied to the inductor, a magnetic field is created, storing potential energy.

The magnetic field generated by the core is accompanied by a voltage loop which is induced in the coil- the greater the magnetic field intensity, the greater the induction voltage. This voltage then builds upon a core foundation the flux induced and the inductance increases. The energy that is stored in the form of current induced varies depending on the design of the inductor; this includes the number of windings on the core, the flux density and the physical size of the component itself.

In classic applications, the rate of voltage change is directly proportional to the rate of current change implemented by an external power source. This produces an output voltage wave-form curve that follows the same shape as the input. For switch-mode power supplies, the rate of voltage change is usually higher and as a result, the output voltage wave-form is of a different form and appears to be "chopped". In motor drives, power controller and thyristors, the rate of voltage change will fluctuate between a relatively high and low rate, depending on the amount of control that is forced onto the wave-forms.

Therefore, the IR02BH1R0J, as a fixed inductor, can be applied to a variety of applications and can withstand high currents and continual use. This inductor is designed in such a way that it is capable of controlling electrical noise and providing transient protection. In simpler terms, the component works by storing potential energy in a magnetic field, which is dependable on the rate of voltage change experienced by the device, and outputting this stored energy at different rates, depending on the surrounding circuitry.
