Seven Fundamental Considerations for Selecting EMI Filters
By Rigoberto Rios, Jorge Varela, and Amanda Ison Virtually every electronic device is subject to and, to at least some degree, must be protected from electromagnetic interference (EMI), or electrical noise. EMI is generated by both naturally occurring and engineered sources ranging from solar flares to cell phones, and, if left unmitigated, diminishes the integrity and … [Read more...]
