Reducing Electromagnetic Interference

Filed under: Articles

Electromagnetic interference. It’s a real pain, am I right? EMI is perfectly awesome when it comes in the forms of thunderstorms or the Northern Lights. But when you’re building an electronic assembly, EMI can cause problems. Fortunately, EMI is easy to reduce.

Meet the toroidal inductor. Toroidal inductors have a symmetrical shape that minimizes the amount of magnetic flux that escapes the core. This, in turn, reduces EMI.
