These components are designed to minimize losses, achieving efficiencies greater than 99% even at high frequencies (from 10 kHz to 500 kHz).
Its compatibility with advanced silicon carbide (SiC) and gallium nitride (GaN) semiconductors allows for the design of more compact and lightweight power converters. This technology offers a wide range of inductance values with high accuracy. The integrated design helps reduce the total cost of ownership.
These components are suitable for demanding applications such as electric or hybrid mobility (aerospace, including eVTOL), military/defense systems, electric energy storage systems and smart grids, and support power levels up to 300 kW.

MML Film Capacitors: High-Density, Reliable Solutions.
Exxelia's MML (miniaturized microlayer) film capacitors achieve up to four times the energy density, offer up to a fourfold size reduction compared to traditional film technologies, and are up to 90% lighter than equivalent multilayer ceramic capacitors (MLCCs). These components are constructed with a non-inductive, stacked metallized polymer film and encapsulated for robust mechanical and environmental protection.
MML capacitors are certified to MIL-STD 202 and have a qualified ESA evaluation. They feature an open-circuit failure mode with self-healing properties, ensuring long-term operational integrity. Furthermore, they maintain stable performance across a wide operating temperature range, from -55°C to +140°C, with capacitance ranging from 100nF to 5000µF and voltage ratings up to 2000V DC. Exxelia also offers customizable MML solutions, including various housing types (D, M, and C series) and custom designs to optimize integration, thermal monitoring with thermocouples, and specific electrical characteristics for unique application requirements.
MML capacitors are used in critical applications such as power converters, power management systems, payloads, telemetry, flight controls, charge/discharge circuits, generators, and electric motors. They are tested to meet various environmental and durability standards, including humidity (MIL-STD-202 Method 103), barometric pressure (Method 105), thermal shock (Method 107), and lifetime testing (Method 108).
