Fixed inductors play an integral role in virtually any type of electronic system. From supplying current to allowing alternating current signals to flow, they provide a critical function, and risk compromising any system’s performance if not working correctly. One of the most reliable fixed inductors is the SC1812-330, a power inductor that is optimized for maximum heat dissipation. Here, we’ll examine the applications and working principle of the SC1812-330.

Applications

The SC1812-330 is a high-current inductor designed for DC/DC converter applications that require high efficiency. These include switching regulated power supplies, notebook computers, and portable electronic devices, such as phones and tablets. It is also frequently used for LED lighting, multi-pair high current DC/DC converter packaging, space-limited applications, and current sensing brushes for dynamic braking applications.

It is usually used for applications with voltages between 3 and 6 volts, and current ratings of 3.3-5 amperes per unit. Devices that make use of the SC1812-330 often require low voltage drop performance, high reliability, and exceptional efficiency. It is capable of sustaining a temperature range as high as 125°C, and much higher than lower-end inductors.

Working Principle

The SC1812-330 is a core-less surface-mount power inductor. It consists of a rectangular coil of wire, electrically connected to two leads. It is designed to facilitate a very-high current through the inductor, without heating up or generating a large amount of noise. It works by passing an electrical current through two terminals stored inside the inductor, developing a magnetic field as a result.

The magnetic field generated by the device resists the current. This property is known as inductance, and inducing it ensures a smooth current flow and precise voltage control, even in the face of changing load characteristics. Typically, the strength of the current is proportional to the magnetic field, making it possible to accurately control the current without increasing the temperature.

Summary

The SC1812-330 is a fixed inductor that has been specially designed for applications that require high efficiency and current ratings of 3.3-5 amperes. Its core-less design ensures very low heating and noise generation, allowing it to be used in space-limited applications and current sensing brushes. As a result, the SC1812-330 has become one of the most reliable fixed inductors for virtually any type of electronic system.
