Introduction to ESD Gun<\/a> Testing and Its Industrial Relevance<\/strong><\/h2>\n

Electrostatic discharge (ESD) poses a significant risk to electronic and electrical equipment across multiple industries, including automotive, medical devices, industrial automation, and consumer electronics. ESD gun testing simulates human-body-model (HBM) discharges to evaluate a device’s immunity to transient electrical disturbances. This article presents a rigorous methodology for ESD testing, with a focus on the LISUN<\/a> ESD61000-2<\/strong> ESD-Simulator<\/a>, a high-precision instrument designed for compliance with IEC 61000-4-2 and other international standards. <\/p>\n
