Fixed inductors are commonly referred to as “reactors” and are a type of inductor used to store energy in magnetic fields. These are basic components of electrical power systems and are used to inductively couple two circuits or to tune connection inductance in network designs. The 103-121FS is a type of fixed inductor incorporating advanced technology which ensures superior performance and reliable operation in various applications. This paper will discuss the applications and working principles of the 103-121FS fixed inductor.

The 103-121FS fixed inductor is designed for use in a variety of space-limited, low-power applications. This includes photovoltaic inverters, uninterruptible power supplies, voltage regulators, and motor controllers. The device has an ultra-small package and a very low DCR, enabling designs with maximum operating flexibility. It can also be used in applications at higher ambient temperatures, such as automotive and industrial motor controllers.

In terms of performance, the 103-121FS fixed inductor has very low DCR, very low EMI and very low leakage inductance. It has a high self-resonant frequency and a very high Q factor. These features contribute to low power losses and improved efficiency in systems where the 103-121FS is installed. This device also has a dielectric absorption test rating of 5V and requires no additional external components.

The working principle behind the 103-121FS fixed inductor is based on the fact that when current passes through a inductor, it creates a magnetic field. This magnetic field stores energy which is then released into the circuit as the current changes. The inductor works by providing an inductive reactance between the two terminals, allowing it to oppose the change in the current. This allows the inductor to behave like a resistor in the circuit, regulating current flow.

In addition, the 103-121FS incorporates design characteristics that allow it to maintain an exceptionally high Q factor even when subjected to high frequencies. This is due to the low parasitic elements such as lead length, which ensure that the inductor can function effectively in a wide range of frequencies. This is essential in applications such as motor controllers and voltage regulators where the frequencies can vary significantly.

Overall, the 103-121FS fixed inductor has been designed with excellent performance and reliability for space-limited low-power applications. The device presents very low DCR and EMI and is capable of operating at high temperatures. It also has the ability to maintain a very high Q factor, even when subject to high frequencies. This ensures optimal performance in an array of applications, making the 103-121FS fixed inductor the ideal choice for any design.
