What is Spherical Silica for EMC?

High‑purity silica particles—spherical in shape—serve as key dielectric fillers in the encapsulation of electronic components. Their uniformity and controlled particle size range (from 0.01 µm to above 20 µm) reduce electromagnetic interference (EMI) while maintaining mechanical integrity. The material’s low dielectric constant and high thermal stability make it indispensable for telecom infrastructure, automotive electronics, aerospace systems, medical devices, and consumer gadgets.
