Fixed inductors, sometimes referred to as chokes, are passive components used extensively in electronic circuits including power supplies. A fixed inductor is characterized by a permanent magnetism within a core structure that in turn creates a magnetic field when current flows through the inductor. It is used to store energy in the form of a magnetic field and can be used for filters, tuned circuits, oscillators, matching networks, or to provide a DC path for AC signals. It is also employed in power supply designs where its inductance helps to reduce the level of noise and ripple in the output waveforms.

The L-15WR15GV4E is a fixed inductor designed for power supply applications. Its main purpose is to minimize noise and ripple in the output waveforms. It comes in a standard EIA 0806 size and has an inductance of 15uH with a tolerance of +-10%. The resistance is rated at 15 Milliohms with a tolerance of +-5%. It has a continuously current rating of 30A and can handle peak current up to 60A.

The basic working principle of the L-15WR15GV4E is that when current travels through the ferromagnetic core of the component, the magnetic field created induces an opposing field. A back emf is then created in the inductor that is opposite to the current that created it. This back emf opposes changes in current and slows the rate of current change in an ac circuit, allowing more time for the voltage to stabilize.

In applications such as power supplies, the inductance of the L-15WR15GV4E helps to reduce noise and ripple in the output waveforms. It has a self-resonant frequency of 1.54MHz, which further reduces noise and ripple. This frequency is also high enough to allow for fast transient response in various applications. The device has a low temperature coefficient, which ensures that the characteristics of the component remain the same over a wide temperature range.

The L-15WR15GV4E has a high power dissipation rating and is capable of dissipating up to 600W of power. This means that the component is suitable for high-power applications, such as personal computing and server systems. It also has a high temperature coefficient, which ensures good performance in industrial and automotive applications.

In summary, the L-15WR15GV4E is an ideal component for use in power supply applications. Its high inductance helps to reduce noise and ripple in the output waveforms, while its self-resonant frequency and low temperature coefficient mean that it can remain stable in various temperature ranges. The component is also capable of handling high power levels and is suitable for use in many high-power applications. As such, it is a versatile and useful component for power supply designs.
