Fixed inductors are electronic components used to control current or voltage flows in electrical circuits. The ER1840-105JR is an example of a fixed inductor which works on the principle of magnetically induced electrical current. This component is most commonly used for applications such as starting and running motors, controlling electrical current in power supplies, and filtering electrical currents in radio frequency circuits.

The ER1840-105JR fixed inductor is composed of a core made of a ferromagnetic material such as steel or iron based metal alloy, copper or aluminum windings, and a wire that is wrapped around the core. This wire creates a magnetic field when an electrical current passes through it. The current and magnetic field interact to create an inductance that can be used to control current and voltage flows in a circuit. This type of inductor is also known as an air-core inductor because its core is generally made of air.

The Physical properties of the ER1840-105JR helps to determine its output characteristics. The inductance is measured in nanohenries (nH) and is usually greater than 10nH. The part also has a rated DC current of 1.43A, resistance of 0.98 Ω, and quality factor (Q) of around 7-25. The core of this inductor is often composed of ferrite, which is a ceramic-like material that has a high permeability and can increase current flow.

The ER1840-105JR works on the principle of magnetically induced electrical current. When an alternating current is applied to the wire, it creates a magnetic field that induces a counter current flowing in the opposite direction. The height of the current and voltage that is produced is determined by the inductance of the core and the load resistance. The current creates a magnetic field that is twice the size of the original current. This is the principle that is used by the ER1840-105JR to control current and voltage flows in a circuit.

The ER1840-105JR fixed inductors are designed for a wide range of applications. They are most commonly used for applications such as starting and running motors, controlling electrical current in power supplies, and filtering electrical currents in radio frequency circuits. These inductors are also used to reduce voltage spikes by providing an inductive path for the current to flow, absorbing the effects of the spike may have on the circuit board and other components. Additionally, they are used in electronic circuits for filtering and signal conditioning applications.

Overall, the ER1840-105JR is an example of a fixed inductor that is used in many different applications to control current and voltage flows in electrical circuits. It is composed of a core made of a ferromagnetic material such as steel or iron based metal alloy, copper or aluminum windings, and a wire that is wrapped around the core. This wire creates a magnetic field when an electrical current passes through it, inducting a counter current and allowing the inductor to regulate current and voltage flows in the circuit.
