myth vs reality

The myth: The representation of shield performance (in dB) as applied to products will...

This document discusses the myth that digital circuit boards can be isolated from conductive chassis structures, explaining the reality that they are always coupled through distributed capacitance and transmission line effects.

Think EMC is just about meeting regulations? Think again. Discover how electromagnetic compatibility's true purpose—ensuring systems work harmoniously with themselves—revolutionized modern electronics design.

ESD standards provide a limited view of electrostatic discharge. Reality reveals a complex spectrum of voltages, rise times, and current peaks that challenge traditional testing methods, exposing potential vulnerabilities in electronic system protection.

Don't be misled by common assumptions about EMI emissions. While many attribute conducted EMI profiles solely to currents from product power connections to LISNs, the reality is more complex. Interface-sourced common-mode potentials can create measurement effects that appear to originate from power terminals—requiring different mitigation strategies than traditional power entry suppression.
