Additionally, due to it current rating and excellent noise suppression, it is used in harmonic reduction circuits and for motor drive applications.

Working Principle: Fixed inductors work by using the principles of electromagnetic induction. They consist of a core of magnetically permeable material wrapped in a coil of wire. When an AC current is applied to the coil, it will produce a magnetic field of strength proportional to the magnitude of the current. This magnetic field is also proportional to the inductivity, or number of windings, of the coil. The magnetic field will induce in an electric trend in the coil and the generated voltage will be proportional to the time rate of change of the current. As the coil is effectively storing and transferring energy, this is known as inductance. The SLF7032T-681MR16-2 specifically works within a frequency range of 80kHz to 1 MHz.

Conclusion: The SLF7032T-681MR16-2 is a fixed inductor designed for surface mount technology. It has an inductance value of 16.8 µH ±10%, a maximum operating temperature of 125 ºC, and a rated current of 1.66 A. This device is used in a variety of applications, including power management and natural frequency tracking in cell phones, snubber circuits, switched-mode power supplies, harmonic reduction circuits and motor drive applications. The device works by constructing an electromagnetic field which induces a voltage proportional to the rate of change of the current. This field is proportional to the inductivity of the coil, and the device works within a frequency range of 80kHz to 1MHz.
