Fixed Inductors: VLC6045T-680M Application Field and Working Principle

Fixed inductors like VLC6045T-680M have countless useful applications in electrical and electronic circuits. As an inductor, their primary use lies in filtering out signals of specific frequencies, especially interference signals. When combined with capacitors, they are also used in LC resonant circuits with different types of batteries, making them ideal in the fields of power supplies, inverters, radio communication systems, and more.

VLC6045T-680M in particular is a surface mount fixed inductor, generally used as EMI filters mainly in applications such as computer peripherals, chargers, and power supplies. It comes with a maximum operating temperature of +125℃ and a ripple current of 6.8A at an ambient temperature of +25℃.

Though the structure of a fixed inductor and its components vary depending on the type and design, its basic working principle is the same. An inductor generates a magnetic field when a current flows through it. This changing magnetic field, in turn, produces a voltage, which is equal to the rate of change of the magnetic field multiplied by the inductance of the inductor.

At the heart of the fixed inductor lies a coil of wire, usually insulated and wound around a cylindrically shaped core material, typically made of steel, powdered iron alloy, or ferrite. The number of turns of the coil and the core material affect the inductance of the inductor. As the current passes through the wire, it creates a magnetic field around the core and the coil. The magnitude of the flux, or the magnetic field, depends on the current.

The other parts of the VLC6045T-680M include a spacer, which separates the core from the outer shell, as well as a terminal block and a connecting wire. The shape and material of the terminal block, as well as the type and length of the connecting wire, also affect the inductance of the device.

To summarize, fixed inductors like VLC6045T-680M have many different applications, but they are generally used in power and signal circuits to filter out specific frequencies. The basic components of a fixed inductor consist of a coil of wire, a core material, a spacer, a terminal block, and a connecting wire. When current passes through the coil of wire, it creates a magnetic field, which in turn produces a voltage, and this voltage is proportional to the rate of change in the magnetic field.
