<h1>Fixed Inductors</h1><p>Fixed inductors, also known as coils in the electric power industry, are used to create magnetic fields. They cannot be tuned, because the inductance must remain constant in order to prevent large fluctuations in the current or voltage. The SP1812-122K is a high performance fixed inductor created by Coilcraft.</p><h2>Application Field</h2><p>The SP1812-122K has a wide variety of applications, including mobile and consumer electronic devices, automotive electronics, power supplies, home audio/video, and telecommunication equipment. It is also applicable in general purpose applications, high frequency switching, and medical equipment.</p><p>This inductor is a low-loss, high-efficiency solution for mobile phones, tablets, wearables and other low-power applications. It operates well at both high and low frequencies and features an inductance range of 0.51-2.2uH in both power and power+Gnd configurations. The SP1812-122K also provides excellent thermal performance with a temperature range of -40°C to +125°C.</p><h2>Working Principle</h2><p>Fixed inductors are used to create magnetic fields in electric circuits. It works by creating a loop of current in a conductive material like copper, which creates a magnetic field. If an AC voltage is applied to the coil, the current flow will be constant and the magnetic field will also remain constant. The magnetic field induces a voltage, which is determined by the inductance of the coil.</p><p>The SP1812-122K is constructed from a ferrite core, a conductive wire, and a housing. The ferrite core helps to keep the induction in the coils constant by increasing its permeability. The coil has two copper circuits – a primary winding made of copper wire and a secondary winding in the center. On one side, the primary winding has the copper wire wrapped around the secondary winding. On the other side, the primary winding has the copper wire wrapped around itself in a closed loop.</p><p>The inductor is designed to usually operate at a frequency range of 50 MHz to 500 KHz. This makes it ideal for a wide variety of applications. The SP1812-122K also features low electrical losses, high efficiency, gold-plated pins, superior heat dissipation, and a strong dielectric barrier to provide better electrical insulation.</p><p>The SP1812-122K is a reliable and efficient fixed inductor that is suitable for a variety of applications in both consumer and automotive electronics, power supplies, and more. It is a powerful inductor due to its low electric loss, high efficiency, wide temperature range, and strong dielectric barrier.</p>The specific data is subject to PDF, and the above content is for reference
