Fixed inductors, also known as “chokes”, are components used to reduce the flow of AC current. They are usually made of a coil of wire wrapped around an iron core. The PM1812-181J-RC is a general purpose inductor designed to perform in a variety of applications.

The PM1812-181J-RC is a radial leaded, axial ferrite inductor. It has a maximum lead wire length of 12.5 millimeters and a maximum body size of 18 millimeters. The rated inductance is 1.8 microhenrys, and the rated temperature range is -40 to 125 degrees Celsius. It has a maximum current handling of 0.8 Amp and a nominal Saturation current of 2.5 Amp. The operating frequency of the PM1812-181J-RC is from DC to 1 MHz.

The applications for this particular fixed inductor generally fit into three main categories: power supply, digital, and RF filtering. For power supply applications, the PM1812-181J-RC functions as a power filter inductor for DC-to-DC converters and other power supply circuits. This prevents the noise from being transmitted, which regulates the output voltage. In digital circuits, the PM1812-181J-RC is used as an input/output filter inductor. This is useful when working with sensitive components or devices that require a steady voltage or current. Finally, in RF filter circuits, this inductor is used to suppress high frequency switching noise generated from devices like phones, cellular radios, and television receivers. This type of noise can cause interference with other components in the system.

The working principle of a fixed inductor is based on the principle of induction. When a current is passed through the inductor, it creates a magnetic field. This field induces a voltage in the coil, which then side forces the current to change. The amount of current the inductor can handle will depend on the number of windings, or turns, the coil has. As the current passes through the windings, it creates a back electromotive force, which is then dissipated as heat.

The PM1812-181J-RC is great for use in a variety of different applications. Its operating frequency, rated inductance, and current handling capabilities make it suitable for power, digital, and RF filter circuits. Its ability to regulate voltage and suppress electronic noise makes it a reliable and efficient component in any electronic system.
