Fixed inductors are inductors which possess a permanent winding and core element without any displacement or adjustment of any kind. This type of inductor is used in a wide variety of power electronic applications such as in DC-DC converters, switching converters, and uninterruptible power supplies. The 1330R-48F is one such fixed inductor, specifically designed for high-current switching power supply applications.

The 1330R-48F is a non-shielded inductor, constructed with two identical ovoid coils. Each coil is composed of a high-temperature, high-reliability grade of ferrite core material. The unique design of this fixed inductor features winding terminals that permit direct connection to the corresponding coil ends and provide longer air voids between adjacent winding turns, resulting in reduced Leakage Flux and greater efficiency. In addition, the 1330R-48F is encased in a rugged, encapsulated body, which results in higher vibration resistance and greater durability.

The 1330R-48F is typically characterized by its typical inductance of 48uH, its rated current of 97A, and its DC resistance of 0.0088 ohms. In addition, the 1330R-48F is capable of delivering a maximum working frequency of 80kHz, resulting in a reasonable level of power conversion efficiency for power supplies operating at higher power levels.

As previously mentioned, the 1330R-48F is most commonly used in high-current switching power supply applications. In such systems, the 1330R-48F serves as an inductive element, typically forming part of a larger power conversion circuit along with other components such as capacitors and voltage regulators. During operation, the 1330R-48F is used to store the energy that is required to drive transient changes in the system load. When the circuit is operating at peak power levels, the stored energy from the inductor will be used to help power the system load during any sudden voltage or current variations in the load.

At a more fundamental level, the working principle of the 1330R-48F can be explained as follows. When a current is passed through electromagnetic devices, such as the 1330R-48F, a magnetic field is created in the inductor, resulting in energy being stored in the device. This stored energy creates a flux linkage between the coils within the inductor, which produces a proportional voltage across the device. This induced voltage creates a counter-EMF (electromotive force), which is proportionally equal to the rate of change of current (ripple) flowing through the inductor. The counter-EMF helps maintain a smooth supply of power to the load.

In conclusion, the 1330R-48F is a fixed inductor, specifically designed for high-current switching power supply applications. The 1330R-48F is characterized by its typical inductance of 48uH, its rated current of 97A, and its DC resistance of 0.0088 ohms, as well as its maximum working frequency of 80kHz. This inductor is used to store the energy that is required to drive transient changes in the system load during the operation of the power conversion circuit. Furthermore, the working principle of the 1330R-48F can be explained as an energy storage inductor, where the stored energy creates a flux linkage between the coils within the inductor, resulting in a proportional voltage being induced across the device.
