Fixed Inductors are a type of passive component used in almost every electronic product. The SP1812R-104J is one such common example.

In terms of application field, the SP1812R-104J is typically used in radio-frequency, like RF interference suppression or signal filtering. In automotive applications, things like rear window defrosters, airbag triggers, ABS systems, CD units, and air conditioning systems all use the SP1812R-104J Inductor. It is also used extensively in certain consumer electronics like laptop and tablets, computers, cellphones, and DVD players. This is due to its high inductance stability, reliable performance, and low cost.

Working principle-wise, the SP1812R-104J consists of two main parts: the core and the winding. This particular type of inductor utilizes a ferrite core. The ferrite core is made up of a specific combination of iron oxide and a few other metals, and works to increase the inductance value while also improving the power supply noise suppression. The winding component is a coil of wires wrapped around the core and is connected to the circuit.

When the Electric current travels through the coil, it creates a magnetic field around the core, which induces a voltage against the flow of current. This process is called mutual inductance. The inductance increases as the amount of turns of the winding around the core increases. The SP1812R-104J also has higher power and heat tolerance than other similar products, making it one of the most popular types of inductors.

In conclusion, the SP1812R-104J is a type of fixed inductors that offers high inductance stability, reliable performance and low cost. It is commonly used in radio-frequency applications such as RF interference suppression or signal filtering. It utilizes a ferrite core and has a winding made up of a coil of wires that is connected to the circuit. The inductance increases with increasing number of winding turns. Its high power and heat tolerance also makes it a preferred choice in automotive and consumer electronics applications.
