In this whitepaper, we take a closer look at the unique characteristics, advantages, and future prospects of PMLCAP technology—a groundbreaking solution that is already generating significant interest across a wide range of applications, from high-end audio systems to demanding aerospace projects.

What You Will Learn in this Whitepaper-Series

PART 1: Introducing the Pioneering PMLCAP Technology

In the first part of this whitepaper, we delve into the manufacturing process and the key characteristics that make PMLCAPs ideal for next-generation technologies.

Thanks to a proprietary vacuum polymerization process and carefully selected materials, PMLCAPs offer significant advantages over traditional film capacitors and MLCCs (Multi-Layer Ceramic Capacitors). Already in use across a wide range of cutting-edge applications—from high-end audio systems and automotive electronics to renewable energy systems and NASA missions—PMLCAPs are unlocking entirely new possibilities.

PART 2: Setting New Standards – PMLCAPs in High-Voltage Applications

In part two, we present the compelling case for RUBYCON’s high-voltage PMLCAPs and summarize the key facts. With the launch of the HPB and HPM series, RUBYCON has set a new benchmark, delivering a powerful alternative to conventional film capacitors. Until now, film capacitors have dominated high-voltage applications due to their excellent insulation, temperature resistance, and frequency stability. However, their limitations—such as bulky form factors, fire hazards, and voltage derating at elevated temperatures—have highlighted the need for more advanced solutions.

These high-voltage PMLCAPs offer superior voltage endurance, enhanced thermal resistance, and a more compact design—opening up new frontiers in power electronics, renewable energy, and future mobility technologies.
