How FR4 Epoxy Sheet Performs Under High Voltage Stress?

FR4 epoxy sheet exhibits remarkable performance under high voltage stress, making it a cornerstone material in electrical and electronic applications. Its exceptional dielectric strength, typically ranging from 20 to 80 kV/mm, allows it to withstand substantial electrical fields without breakdown. This resilience stems from its composite structure of woven glass fiber reinforced with epoxy resin, creating a robust barrier against electrical discharge. Under high voltage conditions, FR4 maintains its insulative properties, preventing current flow and protecting sensitive components. Its low moisture absorption further enhances its electrical stability in varied environments, ensuring consistent performance even in challenging conditions. This combination of properties makes FR4 epoxy sheet a reliable choice for high voltage applications, from power distribution systems to advanced electronics.
