Look at different types of through-hole and surface mount inductors. Learn about the key characteristics of inductance, DC resistance, and maximum current to consider when choosing inductors for a project. Explore how to combine inductors in series and pa
- [Instructor] Inductors are sometimes easy to recognize…because they look like a bunch of coiled wires.…If you've ever looked inside some…of your larger electronic devices,…you've probably seen inductors that look like this.…Most likely, located near the device's power supply.…The majority of inductors that you'll find will have…their wires wrapped around a ferromagnetic material…like iron or ferrite,…which acts as the inductors's core to enhance…the magnetic field.…Having the core enables the inductor to have a higher…inductance and store more energy using fewer loops of wire.…
There are three main characteristics to look…for in an inductor.…The first is the inductance, which will be measured…in units of henrys.…Additionally, the conductor will have a certain…amount of DC resistance,…which is the resistance of the wires in the coil…when a constant current is flowing though it.…This will usually be pretty small,…less than a single ohm.…The third specification to look for…is the maximum current that the inductor can handle.…
