Fixed inductors are passive electrical components used in electronic circuits to induce magnetic fields. SP1812R-104K is a fixed inductor product manufactured by a top electronic components company in the world today. Its application field is quite broad, it can be used in various kinds of filter circuits, circuits that use switching power supplies, LCD Applications, and so forth. As its name suggests,the “SP” implies that it is designed with special specifications. The segmented “18” part of the name represents a maximum height of 18 mm and the height of the overall product is 8 mm. The “12R” means that its exterior diameter is only 12 mm, and the “104K” reveals its inductance value which is 104 mH. Here are some of the particulars of this particular product:

Operating temperature ranges from -55 to +125 degrees Celsius.
Resistance is set at 1.2 Ohm +/- 30%, with insulation resistance up to1000 MOhm.
Saturation current is 6.7 A and test current is 4.5 A.
The Q Factor of this product is 65 at 100 KHz.
It is designed to be high in sensitivity and low in leakage, with core travel loss within 0.2 mH/A.
The lead type is amorphous.

The demonstration of the working principle of the SP1812R-104K is based on the principles of electromagnetic induction. Fundamentally, this type of inductor can provide voltage that is proportional to the current flowing through it, thanks to the relationship between voltage and magnetic fields, better know as Faraday’s Law of Electromagnetic Induction. The inductor has a coil of wire wrapped around a core that stores energy and induces an electric current, which in turn produces an opposing magnetic field. This is due to the fact that whenever a voltage is induced, an electric current will flow through the coil, creating a magnetic field. As the current changes, so does the strength of the magnetic field, creating a voltage drop or surge throughout the circuit.

It has become increasingly common for people to use SP1812R-104K in various projects, as it is a reliable, efficient, and low-cost inductor that is simple to install and use in an electronic circuit. In addition, this product has excellent insulation capabilities and is highly suited for high-frequency applications with its superior resonance performance and Self-resonance rate control. It is also highly heat-resistant and shockproof.

In conclusion, SP1812R-104K is a great fixed inductor product with very wide application fields. It works on the principles of Faraday’s law of electromagnetic induction, utilizing a core and a coil of wire wrapped around it to create a magnetic field that induces an electric current. It is extremely reliable, offers excellent insulation, and is highly suitable for high-frequency applications. With its simple installation process, it is the perfect solution for many electronic applications.
