This episode of Inside Electronics explores how a “power renaissance” is reshaping electronic design, with capacitors playing a central role. Host Alix Paultre speaks with Eduardo Drehmer, VP of Product Marketing at TDK, about rising power demands from AI, data centers, and electric vehicles, and how this pushes efficiency, thermal management, and reliability to the forefront.

Alix and Eduardo explain how multilayer ceramic, aluminum electrolytic, and film capacitors each evolve to manage higher voltages, large surge currents, and harsh automotive environments while maintaining long lifetimes.

They also highlight TDK’s broad portfolio, from board-level MLCCs to capacitors used in fusion power projects and discuss how automotive reliability standards now influence industrial designs. The discussion closes on global manufacturing, supply stability, and safety challenges in EV batteries, with TDK and DigiKey partnering to make the latest capacitor technologies widely accessible.
