Fixed Inductors are important components in many electric circuits. The CAL45VB120K is a series of fixed inductors from Jiangsu Changlong Electronic Co. Ltd, designed as part of the firm’s power supply solution products. The CAL45VB120K is an open frame power inductor that has a high current rating and the smallest possible size.

The purpose of fixed inductors is to store or release energy in the form of a magnetic field or when the electrical current running through them changes direction or intensity. This process is known as inductance and is one of the fundamental processes related to electricity. Fixed inductors can be used in a variety of ways, ranging from stabilizing circuits during electrical surges, to generating a remarkable level of low-distortion in audio signal processing.

The CAL45VB120K is especially useful for power supply solutions for consumer electronics such as net-tops, notebook computers, and media players. It has a high saturation current of 12A and a rated current of 10A. It also has a small size, with a width of 5 mm and height of 4.5 mm. In comparison to other similar inductors, the CAL45VB120K boasts a comparatively low DC resistance, which allows it to achieve superior overall power efficiency.

The working principle of the CAL45VB120K is based on the use of miller capacitance and distributed capacitance to compensate for the flux variations caused by the passing of the electrical current. Miller capacitance is a basic form of electrical capacitance characterized by the intermetallic layer under an insulating layer. The insulating layer enhances the conduction of current, while the layer of intermetallic allows the inductor to store higher levels of energy. This process, coupled with distributed capacitance, enables the CAL45VB120K to provide an excellent power efficiency and low distortion.

The CAL45VB120K offers the highest quality of inductance performance amongst a wide variety of power supply solutions. Its small size, high magnetic saturation, DC resistance, and low power dissipation make it an ideal choice for a large range of consumer electronics. The combination of miller capacitance and distributed capacitance allows the inductor to provide efficient power transfer, low distortion, and high-efficiency performance.
