Fixed Inductors are components designed to store electrical energy in the form of a magnetic field. The S1812R-681J is a high-performance Fixed Inductor that has a wide range of applications. It is a practical and economical choice for designers of electronic systems such as power supplies, filters, and oscillators.

Generally speaking, the S1812R-681J inductor is a small, sealed and self-supporting component made of a thin metal core. The inductor coil has a wire-wound winding, which is insulated and wound in a cylinder. It features a maximum inductance of 0.681µH ( at 1kHz, 0.1 Vrms), a dc resistance of 0.09mΩ and a Self Resonant Frequency (SRF) of 28MHz. The inductor also has a good temperature coefficient and low hysteresis, enabling it to perform consistently under a wide temperature range.

The S1812R-681J inductor is highly versatile, which allows it to be used in various applications such as power supplies, filtering, and oscillators. In power supplies, it serves to regulate the current flow, providing a constant voltage to the load. The low dc resistance of this inductor also enables it to remain stable during overcurrent conditions. In filtering applications, the inductor can be used to block the flow of unwanted signals. It can also be used to reduce noise and adjust phase shift between the input and output signals.

In oscillators, the inductor works in conjunction with capacitors to create an oscillator circuit. An oscillator is an electronic circuit that is used to produce a periodic output signal. When current flows through the inductor, it will create a magnetic field that will store energy, and this energy will be used to react to the current and cause an oscillation between the inductor and capacitor. The oscillation will continue until the original energy is dissipated.

The S1812R-681J Inductor can operate in a wide temperature range and is capable of withstanding high voltage spikes. This makes it a reliable and cost-efficiency option for designers who require low losses and wide temperature range. It is also suitable for high power applications such as broadband filter design.

In conclusion, the S1812R-681J is a reliable and cost-efficient Fixed Inductor that offers a wide range of applications for power supplies, filters, and oscillators. This inductor is highly durable, able to stand up to temperature changes and withstand high voltage spikes. The S1812R-681J Inductor offers designers excellent performance, low losses, and is suitable for high power applications.
