SIG/GND/SIG + PWR/GND Stackup SIG/GND/SIG + PWR/GND Stackups: Will This Work in 4-Layer PCBs? The most popular 4-layer PCB stackup is signal/GND/GND/signal, but what about signal/GND/PWR/GND?
Class X and Class Y Safety Capacitors How to Use Class X and Class Y Safety Capacitors Safety capacitors are used on the input stage of power supplies and on isolated power supplies to reduce EMI and ensure galvanic isolation at low frequencies.
Human Body Model in EMC Overview of the Human Body Model in EMC The human body model provides a description of charge accumulation and discharge from the human body, and it provides a way to understand how charge redistributes into a circuit during ESD.
Should a Capacitor Be Used For ESD Protection? Should a Capacitor Be Used For ESD Protection? Capacitors are not capable of fully protecting a system from ESD, other components are also needed for comprehensive protection.
