Fixed inductors are electrical components used to achieve fixed inductance which are essential to the operation of electrical circuits. In this article, we will discuss the 1331R-822H application field and working principle, a type of fixed inductor.

The 1331R-822H is a high-current, low-inductance, metal-oxide-semiconductor, field-effect transistor (MOSFET) vertical power inductor. It is suitable for DC/DC converters and offers low characteristics such as current rating of 40A and inductance of 8.2mH.

The main application field for the 1331R-822H is in DC/DC converters. As a vertical power inductor, it is suitable for applications that require small electrical sources such as the main power supply, intermediate voltage source, pre-regulator and standby power supply. It is also used in various types of voltage converter circuits such as DC-DC buck converters, boost converters, flyback converters and SEPIC. It can also be used in voltage regulator circuits and step up/down voltage regulator circuits.

The 1331R-822H is designed with a rectangular air-core inductor that uses a ferromagnetic core material to reduce parasitic resistive losses. The use of a ferromagnetic core also helps to increase the inductance and decrease the core size of the device. Further, the inductor is also equipped with a shorting loop to ensure that it is not affected by EMI or vibration.

The basic working principle of the 1331R-822H is based on Faraday\'s law, which states that when a conductor is exposed to a changing magnetic field, a flow of electricity will be induced in the conductor. This flow of electricity produces an inductive voltage or current, which is proportional to the rate of change of the magnetic field. In the case of the 1331R-822H, a high-current flow is induced in the coil when the applied voltage is changed. This creates a large power inductor for DC/DC converters.

In summary, the 1331R-822H is a type of fixed inductor which is mainly used in DC/DC converter applications. It is designed with a rectangular air-core inductor and ferromagnetic core material to reduce parasitic resistive losses. Its working principle is based on Faraday\'s law of induction, where a high-current flow is induced in the coil when the applied voltage is changed. This produces a large power inductor for DC/DC converters.
