Fixed inductors refer to components that generate a constant inductance when energized. This is very different from the variable inductors that can alter the inductance when in operation. Therefore, fixed inductors are used when a constant inductance is necessary. Generally, there are two types of existing fixed inductors – the air type inductor and the ferrite type inductor. The P1330R-684K is a ferrite chip inductor.

The fundamental characteristic of P1330R-684K is the maximum allowed current. In other words, the current rating of this ferrite chip inductor is 3.48A in a given ambient temperature. Beyond this level, permanent damage occurs to the inductor, which makes this current rating a key factor to consider when using this particular model of inductor. Wired in series, the effective inductance is 8.2uH, which can be used in wide range of applications.

The application fields of the P1330R-684K are mainly in devices and appliances that require specific purposes such as medical equipment, home entertainment, computers, telecommunication and automotive electronics. With the low DC resistance feature, the ferrite chip inductor is also widely used in DC-DC converters and filters.

The working principle of the P1330R-684K lies in the coiling of an electric conductor in a magnetic material with the Electric circuit or the magnetic field. The conductor embedded in the magnetic material is known as an inductor, and when Power is applied, the inductor stores energy in the form of a Magnetic field. As the current circulating through the inductor increases, a back EMF is generated, which helps to regulate the current.

In summary, the P1330R-684K is a ferrite chip inductor with an excellent current rating of 3.48A, as well as an effective inductance of 8.2uH. Suited for a variety of applications that require a constant inductance, such as medical equipment, home entertainment, computers, telecommunication and automotive electronics, the inductor works by generating a back EMF in order to regulate the current.
