Welcome to this installment of EE Classroom on Inductors
Electrical circuits just can’t do their thing without them. Used alone as a low-pass filter, with capacitors and resistors to create filters, or to store electromagnetic energy in the magnetic and electric field, inductors enjoy applications in multiple areas from consumer electronics to automotive to healthcare. Within these and many other sectors, this simple coil of wire wound around a central core plays a major role in the critical power management functions. Design engineers have choices — lots of them — so carefully weighing quality, price, support, and a design “best-fit” is time well spent.
In this classroom, we’ve curated resources to help you make the most of that time. Are you choosing inductors for energy efficient power applications or other filtering? We’ve got some basics for that. What’s are the causes and solutions to differential and common-mode noise? We’ve asked and answered that for you, too. And has it been a while since you touched base with Maxwell’s equations? Skip the dense math and read about what the equations really mean. Finally, four additional resources guide you through inductor specifications, application frequencies, voltage ranges and ratings.
No need to take notes — we’ve got you covered.
