Fixed inductors help to store energy mechanically in the form of their magnetic field or as an electrostatic field. Inductors are commonly used for filtering applications, such as electromagnetically coupled radio frequencies (RF) and current transformers. The S1812R-824F is one such inductor, and it is specifically designed for use in high-impedance power factor correction (PFC) circuits. This inductor can be used in both switch-mode power supplies (SMPS) and low-noise applications such as audio preamps, and has a wide operating temperature range of -25°C to +105°C.

The S1812R-824F is a radial leaded, surface-mounted, high-current inductor. It has a maximum DC resistance of 0.95 Ohms and a rated current of 24A. Its inductance ranges from 8.2 µH to 24 µH and it is rated for a maximum voltage of 50V. The inductor is also capable of high-frequency operation, with high-saturation capability that gives it excellent performance even at high-frequency applications.

The S1812R-824F\'s unique construction provides for a high current capacity and excellent high-frequency performance. Its core is made of high-permeability ferrite material that provides a high inductance, low-DC resistance, and good saturation characteristics. The winding is constructed using highly-conductive copper, allowing for an excellent current-handling capacity even at the high-temperature range of this device. In addition, the unique shape of the winding allows the magnetic field to be highly concentrated, allowing for a greater inductance compared to a plain wire winding.

The working principle of the S1812R-824F is fairly simple. When a voltage, or current, is applied to the device, the coil will generate a magnetic field. This magnetic field will then induce a current in the core, which in turn generates a current in the copper winding. The current then flows through the winding, and the resulting magnetic field has a strong influence on the inductance of the device. Since the inductance is directly proportional to the amount of current, it can be adjusted by altering the applied voltage or current.

The S1812R-824F offers excellent high-frequency performance, low-DC resistance, high-current handling capacity, and unique design features that make it suitable for use in high-impedance PFC circuits and SMPS. Its wide operating temperature range makes it an ideal choice for applications where high reliability is essential, and its excellent high-frequency performance makes it an ideal choice for audio applications as well as for signal conditioning and power supply design.
