Fixed Inductors are widely used in industrial, automotive, communications, and consumer markets in products such as digital switching, interfacing, amplifiers, power supplies, and electronic filters. The SP1812-272G Inductor is a kind of fixed inductor with excellent performance. Generally, the function of an inductor is to store the energy in the form of magnetic field and it is also used to restrict the flow of alternating currents in a circuit. Herein, we will discuss the application field and working principle of the SP1812-272G Inductor.

The SP1812-272G Inductor has an inductance of 0.027mH at 1KHz. It has an rated current of 620mA that can generate 450mOhms of DC resistance at room temperature. It also has a high efficiency up to 35%, a low coil loss up to 500mW at 1KHz, and a self-resonance frequency up to 20MHz. Due to the high efficiency, the inductor can be used in various applications such as motor control inverter drives, point of load, switching power supplies, and audio amplifiers.

The working principle of the SP1812-272G Inductor relies heavily on the magnetic flux produced by the turning windings. When a current is applied to the inductor, the inductor will create a magnetic field with a force proportional to the current flowing through the wire. This magnetic field will store energy in the form of a magnetic field. This stored energy is released in the form of an electromotive force (emf) when the current decreases or stops abruptly. This emf acts opposite to the current flow, thus destabilizing and reducing the current flow, leading to a smoother transition of the current.

The SP1812-272G Inductor is the best choice for applications that require high efficiency and low loss. It is designed to keep inductance at a constant level when used at high frequencies, more than 1KHz. Due to its high efficiency, the inductor can be used in various applications that need to dissipate heat, such as motor control inverter drives, point of load, switching power supplies, and audio amplifiers. Therefore, it is a suitable inductor in many applications.

To summarize, the SP1812-272G Inductor is a kind of fixed inductor with an inductance of 0.027mH at 1KHz. It has a rated current of 620mA, a high efficiency up to 35%, a low coil loss up to 500mW at 1KHz, and a self-resonance frequency up to 20MHz. The working principle of the inductor relies heavily on the magnetic flux produced by the turning windings. It is the best choice for applications that require high efficiency and low loss. Therefore, it is a suitable inductor for motor control inverter drives, point of load, switching power supplies, and audio amplifiers.
