The Miniature Micro-LayerTM (MMLTM) capacitors are what it calls “a breakthrough technology that allows tremendous size and weight reduction thanks to an unrivaled energy density.”
“Why is it a game changer? Because an unparalleled energy density of 400 J/dm3 allows for a tremendous reduction in size and weight compared to traditional Polypropylene or Polyester dielectrics, together with an increased operating temperature up to 140°C and transient voltage protection,” the company explained.
“MMLTM capacitors offer a large flexibility in design, easily allowing low profile configurations. Several studies have been conducted on actual cases of controls and DC-Links functions for aircraft applications. All have shown about 50% reduction in size and weight compared to other film technologies.”
MLCC demonstrates a “between 70% to 90% reduction in weight, while showing no capacitance derating with voltage applied and a low drift 5% through the temperature range. Applications using clusters of stacked MLCCs can now be replaced by a single MMLTM unit of similar size, with all of the increased reliability that film dielectric offers.”
The company adds that the MMLTM capacitors are perfectly suitable for power supplies, DC-links, AC/DC/AC power converters, charge/discharge or power generation functions of commercial/military aircraft, satellite platforms and payloads, launchers, defibrillators, downhole tools and any applications of confined electronics.
