PTHF100R-121

Fixed inductors are electronic devices consisting of two terminals wound together on a core material. The premise being that inductors exhibit an Iron Law, which states that inductance of an inductor is directly proportional to the number of turns in the winding and inversely proportional to the space between them.

The PTHF100R-121 fixed inductor is one of the most commonly used inductors in the market, bringing a number of unique advantages. It offers a wide range of inductance values, from 0.22 to 470µH, enabling the wide range of applications. It also has a low DC resistance allowing it to gain a power accuracy of up to 90%, while providing robustness and good performance throughout its lifespan. These characteristics make this particular inductor a top pick for applications requiring accurate control and long-term reliability.

The wide range of PTHF100R-121 inductance values can be used in a variety of different applications. For instance, it can be used in a variety of power electronics designs such as voltage regulators, power converters, switching or linear power supplies, and many more. This type of inductor can also be applied in other types of electrical circuits, like pulse transformers, notch filters, antennas, coupled inductors, and more.

In terms of working principle, an inductor is represented by two parallel paths having one winding on each of them. The element which decides the inductance of the device is called a “magnetic core”. This magnetic core is made up of a ferromagnetic material and it is responsible for storing the magnetic energy. The inductance is given by the relationship between the magnetomotive force, which is caused by the windings, and the magnetic flux density inside the core. In the case of the PTHF100R-121, the core material is air, and the inductance is directly dependent on the number of turns and the inter-winding distance.

In a nutshell, the PTHF100R-121 fixed inductor is very versatile and can be used in a variety of applications. It is a high-quality, reliable device with a wide selection of inductance values. With its accurate control and long-term reliability, it is a great choice for any application requiring a high-performance and dependable inductor.
