Fixed inductors, sometimes called coils, chokes, or reactors, are passive electronic components that store energy in the form of a magnetic field. SP1812-153K is the designation of a particular type of fixed inductor manufactured by Foshan (Fatorco) Technology Co., Ltd. The SP1812-153K is a self-supporting, radial lead, clockwise wound, axial mounting wire-wound inductor. It is available with various inductance values.

The SP1812-153K has a wide range of applications including power supply filtering, signal filtering, noise suppression, and signal isolation. It can also be used as an active electronic component in circuits performing such tasks as voltage level shifting, current limiting, and power factor correction. It is typically used in communications equipment, medical equipment, automotive electronics, robots, power system converters, and industrial automation systems.

The working principle of the SP1812-153K is the same as any other fixed inductor. When a current is passed through the coil, it creates a magnetic field. This magnetic field resists any sudden changes of current, providing the filtering action necessary in many applications. The inductance value of the SP1812-153K, determined by the number of windings and the coil diameter, determines its filtering characteristics.

In order to use the SP1812-153K in a circuit, it must be connected, usually to two leads that allow the current to pass through. The current passing through the coil creates a magnetic field around it that is proportional to the current. This magnetic field can be used to induce a voltage across the terminals of the resistor, or to store energy for later use.

The SP1812-153K has two main characteristics, inductance and Q-factor. Inductance is a measure of the magnetic field strength produced by the inductor and is measured in units of henries. The Q-factor of an inductor is a measure of its efficiency and is typically expressed as a numerical value ranging from 1 to 10, with higher values indicating higher efficiency.

The SP1812-153K also has a wide temperature range, from -40°C up to 125°C, and is UL-rated. It is designed to be robust and reliable, with excellent electromagnetic shielding and high temperature and humidity resistance. The SP1812-153K is an ideal choice for a wide variety of applications requiring robust fixed inductors.
