Fixed inductors are inductors whose inductance value (or, in other words, their ability to oppose the changes of electric current) remains virtually unchanged over a wide range of applied voltages and frequencies. As such, they are commonly found in power electronics applications where the amount of inductance has to remain fixed and the current must remain stable in order to ensure proper operation of the device.

The SLF6045T-1R5N4R0-3PF is a type of fixed inductor that is primarily used in power circuit applications such as DC-DC converter power supply and other applications where stability of inductance is important. The maximum inductance value is 1.5mH, while the rated current is 20mA. The 3PF indicates the temperature coefficient of inductance which is +20%. This indicates that the inductance will increase by up to 20% at the maximum rated current, as the temperature increases.

The SLF6045T-1R5N4R0-3PF fixed inductor has the following main working principle. When a DC current is passed through the inductor, a magnetic field is created, which stores energy in the form of current. This stored energy is the energy absorbed by the inductor before it reaches its maximum rated current. As the current increases, the magnetic field increases, and it is this increasing field that increases the inductance. This, in turn, causes the voltage across the inductor to increase at an increasing rate. As the voltage across the inductor approaches its maximum rated value, it begins to saturate. This saturation occurs when the magnetic field cannot continue to increase and holds the inductance at its maximum value. This saturation will limit the amount of current supplied to the circuit and thus prevent it from overloading.

In summary, the SLF6045T-1R5N4R0-3PF fixed inductor is an ideal choice for power circuit applications that require the stability of inductance and an increased level of protection from overloading. It is suitable for DC-DC converter power supply as well as other applications that require a predictable and stable inductance. Its 3PF temperature coefficient of inductance ensures that its value remains within acceptable variance as the temperature of the surroundings fluctuates. Together, these features ensure that the SLF6045T-1R5N4R0-3PF inductor can be trusted to provide reliable performance for many years.
