Fixed inductors are electronic components that provide a controlled amount of inductance in electrical and electronic systems. The SC3316F-100 (Silicon Chip Technologies) is a specially designed fixed inductor with an inductance value of 100uH at 200KHz. It provides an effective way to reduce the amount of power that is lost due to resistor energy losses. This highly efficient schematic of the SC3316F-100 is shown below.

What is a Fixed Inductor

A fixed inductor is an electronic component that is designed to have a specific amount of inductance. It works by passing a current through a coil, which then induces an opposing magnetic field. This magnetic field will store energy, which gives rise to inductance. Inductors can increase the voltage, current or power levels of a circuit and are often used to filter AC noise from audio signals or to increase the switching speed of digital circuits. Common fixed inductors are toroidal coils, air core coils, surface-mount inductors and ferrite core inductors.

The SC3316F-100 Application Field

The application of the SC3316F-100 is primarily in motor control systems where power efficiency is paramount. The inductor allows for efficient power utilization by creating an inductive voltage load and thus controlling the current, resulting in increased efficiency for motor control circuits. It is also suitable for other types of switching circuits such as boost converters and flyback converters, which require an inductive element to operate. Furthermore, the SC3316F-100 is an ideal candidate for frequency converters as it is able to handle frequencies up to 200KHz.

SC3316F-100 Working Principle

The SC3316F-100 is constructed of two coils that run in series-parallel and are connected in series with a capacitor. The series-parallel construction allows for a larger amount of inductance at lower frequencies than would be found for a single coil. A voltage is applied to one end of the inductor and the current direction is determined by the AC phase. The capacitor is connected across the inductor in series so that it can absorb a portion of the inductive power and store it as energy. The power is then dissipated as a current through the inductor.

The inductive voltage load created by the SC3316F-100 prevents the current from flowing rapidly, preventing the occurrence of excessive heat and current flow. It also enhances the power efficiency of the motor control circuit, as the power is stored in the capacitor and then used over a longer period of time. The frequency range in which the SC3316F-100 is able to deliver is relatively narrow, as the frequencies are limited to 200KHz.

Conclusion

The SC3316F-100 is a fixed inductor designed by Silicon Chip Technologies that has an inductance value of 100uH and is suitable for motor control systems, frequency converters, and other switching circuits. The series-parallel construction allows for increased inductance at lower frequencies, while the capacitor is connected across the inductor in series to store energy and dissipate it as current. The SC3316F-100 is able to handle frequencies up to 200KHz, providing increased power efficiency for motor control circuits and other applications.
