What is an inductor, its purpose, and how does it work? Inductors are an electrical component made essentially of a coil of wire, often wound around a magnetic core. From our experts, here are some facts to help you better understand this technology.   What is the Purpose of an Inductor? The purpose of inductors are that…

When it comes to transformer design, there is an equation most of us are familiar with. This transformer equation is known as the “transformer design equation”. This transformer equation is applicable for inputs that are of most any voltage. The usual voltage forms are sinusoids as seen in lower frequency silicon steel type transformers such…

Predicting the final temperature of a part is not always an easy thing to do. It becomes a complex task for complex parts. We’re going to predict this final temperature for something simple, like air coil inductors. The mathematics found can “loosely” be applied to more complicated parts but certainly, the approach can be applied…

The impedance of an inductor is proportional to its inductance and the frequency of the signal passing through it. Inductors, therefore, can act like low-pass filters, that is they allow low-frequency signals to pass through them, while they block higher frequency signals. A common mode choke inductor is a special type of filter with two…

Who Invented the Inductor? The use of electrical transformers and inductors in the electrical realm is such common practice that it’s hard to imagine a world without these devices. When the property of inductance was discovered in the 1830s by Joseph Henry and Michael Faraday (separately and on different continents), technology was revolutionized. Inductance was…
