Fixed Inductors are used in various applications where a constant inductance is required and the inductive reactance changes by an alternating current. The 1330R-74G is a fixed inductor whose working principle and application are explained in this article.

In general, a fixed inductor consists of a coil of wire whose inductance does not change with an alternating current. The 1330R-74G is a common-mode filter inductor with an inductance of 5.2 mH. This inductor is designed to be used in low-frequency high-current applications, and its housing is designed to be able to withstand RFI and EMI interference.

The working principle of a fixed inductor is based on Faraday\'s law of induction. This law states that an electric current flowing through a conductor induces a magnetic field surrounding the conductor. When this magnetic field flux changes, a voltage is induced across the ends of the coil. This induced voltage is opposing the cause of the flux change and so causes a stabilizing current to flow, which opposes the primary current.

The 1330R-74G is primarily used in power supplies and AC/DC converters. It can be used to absorb the high-frequency electromagnetic interference that is generated by electronic equipment. It also acts as an amplitude limiter, allowing users to control the output voltage at higher current levels. Additionally, it reduces the peak-to-peak alternating current by introducing a low-inductive reactance.

The 1330R-74G can also be used in batteries, particularly lithium-ion and nickel-metal-hydride batteries, to protect them from overcharging and short circuits. Its high inductance enables it to absorb a large amount of energy, thus limiting the current flow and preventing damage to the battery.

In powerchips and DC/DC converters, the 1330R-74G can reduce the high-frequency output voltage ripple, thus increasing the efficiency and reliability of the power conversion. It also helps to reduce the electromagnetic interference from power numbers, improving EMI performance. Moreover, it can reduce the power dissipation of the power chips, thus allowing users to create more efficient systems.

The 1330R-74G is a great solution for many applications where a constant inductance is required. Its high inductance and ability to withstand RFI and EMI make it an ideal choice for power supplies, AC/DC converters, and battery protection. Furthermore, its low inductive reactance allows for more efficient power conversion and less EMI interference.
