Miniature micro-layer capacitors reduce size and weight
Distributor, New Yorker Electronics has added Exxelia’s latest Miniature Micro-Layer (MML) film capacitors. The manufacturer says they are a “breakthrough technology” that allows “tremendous size and weight reduction thanks to its high energy density”.
Energy density is 400 J/dm3 which allows for a substantial size/weight reduction compared to traditional polypropylene or polyester dielectrics, says the company. They also offer an increased operating temperature up to 140 degrees C and transient voltage protection.
The MML capacitors’ capabiities allow low profile configurations. Studies conducted on actual cases of controls and DC-Links functions for aircraft applications show around 50 per cent reduction in size and weight compared to other film technologies, says the company. Compared with multi layer ceramic capacitors (MLCCs) the MML capacitors demonstrate between 70 to 90% reduction in weight, while showing no capacitance derating with voltage applied and a low drift (less than five per cent) through the temperature range, reports the company. 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, it adds.
The Exxelia MML capacitors are suitable for power supplies, DC-links, AC/DC/AC power converters, charge/discharge or power generation functions of commercial and military aircraft, satellite platforms and payloads, launchers, defibrillators, downhole tools and electronics where space is confined.
Samples of the MML capacitor are readily available from New Yorker Electronics upon request.
New Yorker Electronics supplies Exxelia film, mica, tantalum, aluminium electrolytics and ceramic capacitors as well as its EMI/RFI filters, magnetics, position sensors, slip rings and rotary joints.
