Fixed inductors refer to passive components that store energy in the form of an electromagnetic field in a coil. SP1812R-332G is a series of fixed inductors with a small footprint and high current capabilities. Its application field and working principle are discussed below.
Application Field
SP1812R-332G fixed inductors are widely used in DC-DC converters, power supplies, TV sets, AV amplifiers, automotive electronics, communications transceivers, computers, and other fields.
SP1812R-332G fixed inductors are ideal components for applications requiring low-profile parts with high current capabilities. They provide outstanding performance in high power applications and can also work in high-temperature environments. In addition, these inductors feature an excellent temperature coefficient, excellent saturation current, and a wide array of inductance values.
Working Principle
A fixed inductor is composed of a conducting winding wrapped around a core. The core can be composed of a ferromagnetic material (such as iron) or air. The energy stored in an inductor is a function of the number of turns on the winding, its cross-sectional area, and the permeability of the core material. An ideal inductor has no loss, so the current and voltage are in-phase.
When an external voltage is applied to the winding, a change in the magnetic flux around the winding induces a counter voltage that opposes the applied voltage. This counteracting voltage creates a "back-EMF" that limits the rate of current change. This is known as the "self-inductance" of the coil. The higher the inductance, the greater the opposition to current change.
The core, by itself, has no effect on the inductance of the coil. However, the core does provide a path for magnetic flux to be concentrated. The permeability of the core material determines how well the core concentrates the magnetic field and affects the inductance of the winding. By using a core composed of a ferromagnetic material, the inductance of the winding can be greatly increased.
SP1812R-332G fixed inductors feature a high-permeability ferrite core and deliberate design of its winding number, wide range of inductance values and high saturation current. This makes them ideal inductors for wide range of applications.
Conclusion
SP1812R-332G fixed inductors are ideal components for applications requiring low-profile parts with high current capabilities. Their construction features a high-permeability ferrite core and a winding number, wide range of inductance values and high saturation current, making them suitable for a wide range of applications.
