Remarkable 50% reduction in size and weight
With unparalleled energy density and a host of advanced features, these capacitors are revolutionizing design possibilities and performance standards in satellite constellations and beyond.
Exxelia's groundbreaking MML™ ultra-high energy density Film Capacitors are revolutionizing the industry, particularly in the context of satellite constellation projects. With an unmatched energy density of 400 J/dm3, these capacitors are changing the game by significantly reducing size and weight compared to traditional Polypropylene or Polyester dielectrics. They can operate at temperatures up to 140°C and offer protection against transient voltage, making them ideal for the demanding environments of satellite constellations.
In satellite applications, MML™ capacitors offer immense design flexibility, enabling low profile configurations. They have undergone rigorous testing and have proven their effectiveness in control and DC-Links functions in actual satellite deployments. In these scenarios, MML™ capacitors have demonstrated a remarkable 50% reduction in size and weight compared to other film technologies.
Moreover, when compared to Multi-Layer Ceramic Capacitors (MLCCs), MML™ capacitors show a substantial weight reduction ranging from 70% to 90%, without any capacitance derating under applied voltage. They also exhibit minimal drift of less than 5% across temperature variations. This means that applications previously relying on stacks of MLCCs can now utilize a single MML™ unit of similar size, offering enhanced reliability thanks to the film dielectric.
The outstanding features of Exxelia's MML™ capacitors render them suitable for a diverse array of applications, including power supplies, DC-links, AC/DC/AC power converters, and charge/discharge or power generation functions in both commercial and military satellite platforms. Whether it's satellite payloads, launchers, or even downhole tools, these capacitors excel in environments where space is limited and reliability is paramount.
