New Yorker Electronics has announced the availability of the new Exxelia miniature micro-layer (MML) film capacitors, a product Exxelia calls a breakthrough technology that allows tremendous size and weight reduction thanks to its high energy density.
According to Exxelia, the new MML line boasts an unparalleled energy density of 400 J/dm3. It allows for a substantial size/weight reduction compared to traditional polypropylene or polyester dielectrics, with an increased operating temperature up to 140° C and transient voltage protection.
Exxelia MML capacitors therefore offer a large flexibility in design by 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.
The comparative picture with multilayer ceramic capacitors (MLCCs) is even more flattering, as it demonstrates between 70% to 90% reduction in weight, while showing no capacitance derating with voltage applied and a low drift less than 5% through the temperature range. Applications using clusters of stacked MLCCs can now be replaced by a single MML unit of similar size, with all the increased reliability that film dielectric offers.
With such remarkable properties, Exxelia’s new MML 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.
