Fixed inductors, such as the LAV35VB680K, are a type of electrical component used to store electrical energy in the form of an electromagnetic field. These inductors are constructed with a coil of insulated wire that is complete with connecting leads. This type of inductor is used principally in AC applications where current needs to pass through the inductor and create an electromagnetic field, thus storing energy for a period of time.

The LAV35VB680K is a surface mount fixed inductor with an inductance of 680 nH and a rated current of 35 mA. It is an auto-insertable component, meaning it can be easily inserted into a printed circuit board without manual wiring. It has two screw terminals with a maximum rated voltage of 16 V. It is mainly used in power supplies, DC-DC converters, linear regulators, and other power conversion applications.

In terms of its working principle, the inductor restricts the AC current against the voltage, owing to the characteristics of the material used. As the current passes through the coil, an electromagnetic field is created and stored in the iron core. This can be likened to a capacitor storing electric charge; the difference is that in the case of an inductor, the surrounding magnetic field is what is used to store the charge. The resulting electromagnetic field is what allows the inductor to restrict the current against the voltage, consuming kinetic energy in the process.

Furthermore, the significant amount of energy being dissipated as heat if the current is suddenly disrupted poses a safety risk to the LAV35VB680K, and thus, it is recommended that a small resistor be used in series with the inductor to limit the surge current. Depending on the application, ferrite core or air-core inductors may also be used.

The LAV35VB680K is a useful component with many applications in power supplies, DC-DC converters, and other power conversion applications. Its ability to store energy in the form of an electromagnetic field can be harnessed to restrict the current flow against the voltage, making it an essential component for many electronic circuits. It is an auto-insertable component with two screw terminals that makes it easy to install, ensuring it can maintain a steady flow of current to power electric circuits reliably and safely.
