Fixed inductors are components that store electrical energy. They are essentially inductors that have a fixed set of parameters determined by the particular media they are constructed from, which means they are not user adjustable. The BRC2518T101K is one such fixed inductor. It is a reliable and low-loss radial inductor, used primarily for power-supply applications.

The BRC2518T101K is constructed using a ferrite core with a 1,000 microhenry inductance at 10 kHz. This makes it a very useful inductor for applications that require high current magnetic fields. This is because it can handle current up to 20 amperes. It also has a moderately low resistance value and low thermal resistance.

The most common application areas for the BRC2518T101K are in power factor correction and high-efficiency LED lighting systems. It is also being widely used in high-current switch-mode power supply designs. In these applications, it is often used in conjunction with other components such as capacitors and resistors to reduce both the output voltage ripple and the power dissipation of the power supply. It can also be used as a part of a resonant induction heating system in order to achieve higher efficiency.

The working principle behind the BRC2518T101K is simple. In an electrical circuit, when current flows through an inductor, it induces a magnetic flux in the inductor. This flux then induces an electromotive force (EMF) in the inductor. This EMF is proportional to the rate of change of current. This means that when the current is increased, the EMF induced in the inductor also increases.

The BRC2518T101K works on the same principle, but with the key difference being that the coil is specially designed not to add any resistance to the circuit. This means that the inductor will act as a dc power source rather than an impedance. This increases the efficiency of the circuit dramatically because no energy is lost due to heating, as is the case with a traditional inductor.

In summary, the BRC2518T101K is a highly efficient fixed inductor, primarily used for power-supply applications. It is designed with a ferrite core to achieve high current magnetic fields and its low resistance and thermal resistance make it particularly suitable for power factor correction and high-efficiency LED lighting systems. The working principle behind it is that an EMF is induced in the inductor as current passes through it, allowing it to act as a dc power source with no energy loss due to heating.
