Fixed Inductors provide stable, precise impedance levels over a wide range of frequencies and currents. The SC1812-101 is no exception. With an inductance of 10uH (±10%), a saturation current rating of 4.2A, temperature coefficient of inductance of 300 ppm/°C, and a self-resonant frequency range of 0.6 to 1 MHz, the SC1812-101 is an excellent choice for a wide range of applications.

In switching power supplies, as well as other dynamic power supply designs, inductors are used to filter out high-frequency noise. This type of noise occurs mainly as a result of the rapid switching currents applied to the output stage of the power supply. The SC1812-101 is an excellent choice for these applications due to its ability to provide low impedance in the desired frequency range while still maintaining a low DCR at higher currents.

The SC1812-101 is also widely used in consumer electronics. For example, it can be used in television sets, DVD players, or car audio systems. In these applications, the most important criteria are accuracy and efficiency. The SC1812-101’s wide temperature coefficient and low DCR make it an ideal option for these applications.

The SC1812-101 can also provide excellent performance in filter applications. In these applications, the inductor must be able to attenuate unwanted high frequency noise from reaching the desired circuitry. The SC1812-101 can be used as part of a low-pass filter to reduce this type of undesirable noise. This makes it a great choice for audio applications as well as other sensitive electronic circuits.

The SC1812-101’s working principle is quite simple. When an inductor is exposed to an AC voltage, it will create a magnetic field. This magnetic field will induce an electric current in the inductor’s coil, which in turn will generate a counteracting magnetic field. This magnetic field will then oppose the initial field generated by the energizing voltage, creating a self-sustaining inductance. This inductance helps to reduce high-frequency noise from reaching the system’s desired circuitry.

In summary, the SC1812-101 is an excellent choice for a wide range of fixed inductor applications. Its excellent temperature and inductance stability, along with its low DCR and self-resonant frequency, make it a great option for power supply, consumer electronics, and filter applications.
