Fixed inductors belong to a family of electronics components, comprising of passive elements that store energy in the form of magnetic fields or electrostatic fields. They are usually made from coils wound around a core material, and are used in a variety of applications, ranging from the simple filtering and noise reduction of electrical signals, to the support of high-amperage loads needed in power electronics. While the working principles behind inductors is relatively simple, they offer a wide range of functions, dependent upon the design and materials chosen.

The SP1812-123K is a high-performance fixed inductor that has been specifically designed for applications demanding higher current capacities and higher inductance levels than traditional passive components.Thanks to its unique composition, the SP1812-123K offers exceptional performance in terms of stability, reliability, and longevity.

The SP1812-123K consists of a metal base material, generally copper or aluminum, usually with a thin layer of insulating material, typically in the form of a varnish to protect the contact points between layers. This is followed by a coil of copper wire which has been wound in such a way as to maximize inductance, and is then sheathed in a protective material, usually an epoxy resin to keep the coil components securely in place and provide a degree of robustness.

When faced with an alternating current, the SP1812-123K acts as an inductor, storing energy in its core in the form of a magnetic field. As the current and voltage alternates, the magnetic field collapses and rapidly releases its previously stored energy back into the circuit in the form of a secondary current. The speed at which this energy is returned to the circuit is determined by the inductance variable of the device; the higher the inductance, the slower the energy is released back into the circuit.

The SP1812-123K can provide its full inductor capabilities up to 3.3 amps. As for inductance levels, the SP1812-123K offers a maximum value of 120 µH, making it suitable for use in applications where very high levels of current must be sustained, while still delivering the desired inductance. Additionally, the SP1812-123K features a very low DC resistance at 1.1 ohm, making it suitable for applications where low heat dissipation is desired.

Finally, the SP1812-123K provides an excellent level of temperature stability when compared to other passive components in the fixed inductors family, with only 0.1% drop in inductance per degree Celsius of temperature change. This means that the SP1812-123K can be used in applications requiring higher-temperature stability with less of a decrease in function.

In summary, the SP1812-123K is an ideal choice for applications requiring high current capacities, high inductance levels, and temperature stability. Thanks to its superior performance in these areas, the SP1812-123K stands as one of the most reliable fixed inductors on the market, and is the perfect choice for any application requiring a dependable, high-performance component.
