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 an air coil inductor. The mathematics found can “loosely” be applied to more complicated parts but certainly the approach can be…

Common Mode Choke 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 is a special type of…

Use of 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 first found by Faraday in a…

An inductor is 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 are Its Main Purposes? An inductor can store energy in the form of a magnetic field.  This is a very useful…
