Fixed Inductors

A fixed inductor, as the name implies, is an inductor with a fixed inductance value or inductive reactance that is already predetermined. It is a passive electronic component which has a coil of wire that stores energy in a magnetic field when current passes through it. Fixed inductors are most commonly used in electronic circuits for filtering, such as AC power line filtering as the inductor provides a high impedance to any AC current. In addition, it can also be used in signal frequency generation, impedance matching, power conversion type electronic circuits, as well as rectification, voltage dividers, and loudspeaker crossover networks.

The 79F391K-RC is a fixed inductor from Taiyo Yuden which is a specialty in technology solutions for consumer electronics and electronic components. It is suitable in motion control, inductive sensor and low EMI suppression applications. The 79F391K-RC has a wire coil construction of 79 turns on ferrite core using 30 AWG, a consistent reliability in temperature range up to 150℃, and most importantly, an operating frequency of 1 MHz with an inductance of 390nH ±30%.

The working principle behind fixed inductor can be described in its simplest form: the inductor is an element which opposes the change in current. It stores energy in the form of a magnetic field when current passes through it. When the current changes, this stored energy is released again in the form of current. This is also known as inductive reactance which is the opposition to the flow of alternating current and it increases with frequency.

When using the 79F391K-RC for motion control applications, it allows the AC current to pass with minimal losses. This is due to its wire coil construction and high operating frequency. As mentioned earlier, the 79F391K-RC has 79 turns on ferrite core, using 30 AWG. This is more suitable for high frequencies due to its stronger inductance. As for inductive sensors and low EMI suppression applications, it reduces electromagnetic interference (EMI) through the use of a small coil of wire around a signal or power line which absorbs the radiation from the EMI noise.

In conclusion, fixed inductors such as the 79F391K-RC are essential components in many electrical circuits and systems. With its high operating frequency and adjustable inductance value, the 79F391K-RC is suitable for a variety of applications, such as motion control, signal frequency generation, impedance matching, power conversion type electronic circuits, rectification, voltage dividers, and loudspeaker crossover networks.
