Dielectric Constant Guide

Why do some insulating materials excel in energy storage while others fail at high frequencies? The answer lies in the Dielectric Constant, a fundamental property that dictates how a material stores and dissipates electrical energy. Far from being a simple static number, $\epsilon_r$ is the pivot point where material science meets electrical performance. Whether you are designing microscopic transistors or high-voltage capacitors, understanding the nuances of relative permittivity is essential for achieving system efficiency. This guide strips away the complexity to explain why this parameter is the backbone of modern electronic design.     Introduction: What is Dielectric Constant?   The Dielectric Constant (εᵣ), also known as relative permittivity, ...
