Fixed inductors are electrical components that can store energy in an electric field when powered. The ISC1812ER220J is one such component–a power inductor–that is capable of dissipating large amounts of power. It is commonly used in applications such as DC-DC conversion, voltage regulation, and power conversion for high-power applications.

The ISC1812ER220J is characterized by a fixed inductance value, specifically 220uH (microhenrys). This value cannot be changed without physically altering the component. It also has an inductance tolerance of 5%, meaning that the actual value may deviate up to 5% away from the stated value. Other important characteristics of the ISC1812ER220J include its rated current, which is 13A; its rated DC resistance, which is 0.0048Ohm; and its saturation current, which is 28.5A.

The working principle of a fixed inductor is quite simple: when a current flows through the inductor, an opposing magnetic field is produced. This magnetic field opposes the change in the current, creating a back EMF (electromotive force). This back EMF has the effect of "reducing/stabilizing" the rate at which the current increases, a process known as inductance. The larger the inductor, the greater its inductance, and as a result, the slower the current increases.

In terms of application, the ISC1812ER220J is mostly used in power conversion and voltage regulation applications. Such applications include power supplies, motor drives, switched-mode power supplies (SMPS), power factor correction (PFC) circuits, and inverters. It is also used in low-noise power filters, anti-EMI/RFI filter circuits, and in high-power converters to reduce switching losses. In addition, it can be used in energy storage and filter circuits to reduce interference from noise sources.

In summary, the ISC1812ER220J fixed inductor is an ideal component for power conversion and voltage regulation applications. It has a fixed inductance value and an inductance tolerance of 5%. The application field and working principle of the ISC1812ER220J fixed inductor makes it suitable for a variety of high-power applications such as power supplies, motor drives, and power factor correction circuits.
