New Yorker Electronics now offers the new Exxelia MML film capacitors, a product the company calls a breakthrough technology that enables remarkable size and weight reduction due to its high energy density. According to the company, the new MML line offers an unparalleled energy density of 400J/dm3. It provides a substantial size/weight reduction compared to traditional Polypropylene or Polyester dielectrics, with an increased operating temperature of up to 140C and transient voltage protection.
The capacitors, therefore, offer considerable flexibility in design by easily allowing low profile configurations. Several studies have been undertaken on actual cases of controls and DC-Links functions for aircraft applications. All have shown a 50% reduction in size and weight when compared to other film technologies. The comparative picture with MLCC is yet more flattering. It demonstrates between 70% to 90% decrease in weight while showing no capacitance derating with voltage applied and a low drift <5% through the temperature range. Applications employing clusters of stacked MLCCs may now be replaced by a single MML unit of similar size, with the increased reliability that film dielectric offers.
With such excellent properties, these new MML capacitors are ideal for power supplies, DC-links, AC/DC/AC power converters, defibrillators, charge/discharge or power generation functions of commercial/defence aircraft, satellite platforms and payloads, launchers, downhole tools and any applications of confined electronics.
