Fixed inductors are specialized electrical components that are designed to add inductance to electronic circuits. The inductors are composed of a conductor that is wound into a coil shape; the inductance of the component is determined largely by the number of turns, the type of conductor, and the size of the core. The SP1812-123G is a fixed inductor designed to simplify circuit design, reduce size and cost, and reduce the materials used.

The SP1812-123G is available in various sizes, with choices of 8, 10, 12, 14 pins in the 0.017-inch small size to the 0.02-inch medium size. Its shape is round and flat with a length of 13.2mm and a width of 5.2mm. The total weight of the product is 2.8g. The color is yellow-green. It can be printed with a variety of letters and numbers.

One of the main features of the SP1812-123G fixed inductor is its strong stability. Standard structure design and copper conductor winding reduce the impact of line loss on inductance, while the copper core wire with high permeability ensures an accurate inductance value. It is equipped with excellent anti-interference ability to increase product reliability. Moreover, its construction was reinforced with proprietary bonding and sealing techniques, allowing it to function under extreme electrical and thermal conditions.

SP1812-123G fixed inductors are commonly used in industrial communication systems, high-frequency switching power supplies, audio amplifiers, HF communication lines, automotive and consumer electronics, supply regulators and various other electronic device circuits. It is suitable for high-frequency circuits because it can reduce the logic noise of the circuit and thus improve its noise immunity. The rated working current of this fixed inductor is 1A and the rated voltage is 250V.

The working principle of the SP1812-123G is the change of current or voltage when voltage or current is applied. When voltage is applied, the resistor reacts to the inductor by creating an electromotive force, or EMF, which opposes the change. Therefore, the inductor can store energy in the form of a magnetic field and return it to the circuit as current. The same can be said when current is applied, as the inductor also opposes and converts the current into a voltage. As such, the inductor will behave like an AC power source, supplying energy back into the circuit.

In conclusion, the SP1812-123G fixed inductor is an effective component to provide energy back into electrical circuits and reduce the logic noise of the circuit. It is strong and durable and can withstand extreme conditions, providing reliable circuit operation. Its wide range of applications makes it a great choice for a variety of circuits and its small size dramatically reduces the cost and materials used in design. Its excellent stability also makes it a no-brainer choice for electronic circuit designers.
