Revolutionising capacitor technology: Exxelia’s Miniature Micro-Layer (MML™) capacitors

The electronics industry is constantly evolving, driven by the demand for smaller, lighter and more efficient devices. In particular, innovations in capacitor technology are becoming increasingly important. To meet this need, Exxelia has developed a breakthrough solution: Miniature Microlayer Capacitors (MML™). The special feature of these capacitors is their unprecedented energy density, enormous size and weight reduction and, as a result, a higher operating temperature compared to conventional materials.

MML™ – Miniature Micro-Layer capacitors: A game-changing technology

The distinctive feature of Exxelia’s innovative MML™ capacitors is the combination of high energy density with reduced size and weight, thus representing an represents an unprecedented advance in capacitor technology.

MML™ capacitors have an impressive energy density of 400 J/dm3 compared to other technologies, surpassing conventional polypropylene or polyester dielectrics, for example. Exxelia achieves the property of increased energy density through the use of innovative materials and a unique manufacturing process.

Another advantage of MML™ capacitors is their smaller size and low weight. Compared to other film technologies, Exxelia’s MML™ capacitors have demonstrated a size and weight reduction of approximately 50% in real aircraft applications where control and DC link functions are critical. In addition, MML™ capacitors offer a weight reduction of 70-90% compared to MLCCs (Multi-Layer Ceramic Capacitors), without compromising capacitance at applied voltage. This makes them an ideal choice for applications where size and weight are important.

 Another aspect is the operating temperatures: the MML™ capacitors developed by Exxelia also feature an extended operating temperature range of up to 140°C, so that they also work reliably in harsh environments. In addition, these capacitors provide protection against transient voltages and ensure the stability and safety of electronic devices. The MML™ capacitors have a low drift of less than 5% over their operating temperature range, ensuring stable and predictable performance.

Practical applications and advantages

Exxelia’s MML™ capacitors have already proven their value in actual cases for control and DC link functions in aircraft applications. By reducing size and weight, these capacitors enable more efficient and compact system designs, contributing to an overall improvement in aircraft performance and fuel efficiency.

In addition to aerospace applications, MML™ capacitors are also suitable for various other industries where high energy density, smaller size and weight, and higher temperature resistance are important. Examples include electric vehicles, renewable energy systems and military applications.

Summary

Exxelia’s Miniature Micro-Layer capacitors represent a significant breakthrough in capacitor technology, offering unparalleled energy density, smaller size and weight, and higher operating temperature. These features make MML™ capacitors an ideal choice for a wide range of applications, particularly in industries where space and weight constraints are of paramount importance. For more information about Exxelia’s innovative MML™ technology and its applications, visit our webpage about MML technology
