Fixed Inductors

Fixed inductors, or simply inductors, are passive electrical components that store and release energy in the form of a magnetic field. They are widely used in various applications ranging from basic power circuits to extremely specialized and complex systems. The CAL45VU222K Fixed Inductor is a type of inductor designed for use in medium current and high voltage applications that require high switching speed and high current stability.

Application Field

The CAL45VU222K Fixed Inductor is used primarily in medium-current and high-voltage applications such as power line supplies, audio amplifiers, high frequency circuit systems, and transformer circuits. It has a current rating of up to 4A and a maximum operating voltage of 85V, making it suitable for high power applications. Furthermore, its high stabilities and wide temperature operating range make it ideal for use in environments where temperature fluctuations and high-heat dissipation are a concern.

Working Principle

The CAL45VU222K Fixed Inductor works according to the principle of induction. It is composed of a coil of insulated wire, usually copper or aluminum, that stores and releases energy in the form of a magnetic field when current is passed through it. When AC (alternating current) is applied to the coils, the magnetic field produced induces an electromotive force in the coil which is then, in turn, used to drive current. This process is known as self-inductance or self-magnetization. In addition, the inductor also acts as a transformer, thereby converting electrical energy into magnetic energy and vice versa.

When a direct current (DC) is passed through the inductor, a magnetic field is created that induces a voltage on the coil. This is known as the induced voltage. The induced voltage produced is proportional to the product of the current passing through the coil and the number of turns of the coil. The voltage thus induced can, in turn, be used to drive current. The inductive coil of the CAL45VU222K Fixed Inductor produces a conservative self-magnetic field that is stable in the presence of temperature changes and does not dissipate over time.

Performance

The CAL45VU222K Fixed Inductor provides excellent performance. It has an operating temperature range of -40 to 85°C and a maximum current rating of up to 4A. The operating voltage range is 1.5 to 85V and the inductance range is 1 to 20µH. In addition, the device is capable of providing up to 40A of transient current with a frequency range of 0.1 to 100kHz. Moreover, it can tolerate frequencies up to 1000MHz and has a high self-resonance frequency of up to 3GHz.

The CAL45VU222K Fixed Inductor features low distortion, high current stability, and low inductance temperatures. It also boasts an excellent current transfer efficiency of up to 95% and fast switching times, making it suitable for tasks requiring high switching speed. Furthermore, the device has an extremely low profile, with its copper coils measuring only 0.7 mm thick. This makes it ideal for compact and space-sensitive applications.

Conclusion

The CAL45VU222K Fixed Inductor is a reliable and versatile device, making it a preferred choice for medium-current and high-voltage applications. The device offers excellent performance with up to 40A transient current, high current stability, fast switching speed, and low inductance temperatures. In addition, it has a very low profile, allowing it to fit into small spaces where other components would not be able to. Therefore, the CAL45VU222K Fixed Inductor is suited to applications where reliability, performance, and compactness are all key requirements.
