Exxelia revolutionary MML™ ultra-high energy density Film Capacitors

Exxelia, a leading manufacturer of ruggedized passive components and sub-systems dedicated to demanding markets, today introduced Miniature Micro-Layer™ (MML™) capacitors, a breakthrough technology that allows tremendous size and weight reduction thanks to an unrivaled energy density.

MML™ is a revolutionary new technology that provides the highest capacitance per volume in film capacitors available on the market. 

MML™ ultra-high energy density Film Capacitors

 

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.

 

Besides, MML™ 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. 

The comparative picture with MLCC 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 < 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 outstanding properties, Exxelia 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.

Samples are readily available on request.

Features & Benefits :

  • Miniaturization of the function : Up to 50% size reduction vs other film technologies ; matching footprint with stacked MLCC
  • Lightweight : 50% lighter vs other film technologies ; 80 to 90% lighter than ceramic
  • No capacitance derating in voltage, stable in temperature (<5% drift through the temperature range)
  • Capacitance from 1μF to 1000μF 
  • Voltages from 50V to 1000V 
  • Operating Temperature -55 °C to +140 °C
  • Highly customizable

Boost your project with Exxelia film capacitors with reduced delivery times!

We are pleased to announce that certain products in our RA and KM film capacitor series, as well as our special PMR range (for the medical and railway markets), now benefit from reduced delivery times.   Reduced lead times for film capacitors of the RA (Polypropylene PP) and KM (Polyphenylene sulfide PPS) families: Indeed, delivery times for film capacitors in the RA and KM ranges have been considerably reduced. Previously, these products had an average lead time of 20 weeks, but through efforts to optimize our supply chain, we have managed to reduce this lead time to just 8 weeks on average! One of the key product of this range is the KM 111 S/T. This high performance film capacitor is ideal for a wide range of applications, such as power electronics, filters, inverters. The KM 111 S/T provides the precise capacitance value needed for special aviation electromechanical applications. With its high operating voltage and high energy density, the KM 111 S/T offers outstanding performance. And now, with a lead time reduced to just 8 weeks, you can incorporate it into your designs faster, accelerating your product development.

In some cases, we have been able to reduce the usual delivery times for these specific products by a factor of 10. This means you can now get the PMR range film capacitors you need in record time! Film capacitors in the PMR range are specifically designed to meet the stringent requirements of medical and railway applications. Their reliability, stability, and extended life make them ideal choices for medical equipment, monitoring devices, rail transportation systems, and more. Thanks to our reduced delivery times, you can now benefit from these advantages without waiting long to receive your products.   PMR EFCO PMR 4 PMR 64

Exxelia adopts laser marking for its products

Laser marking is part of the GREEN approach that Exxelia has recently implemented for its products. Indeed, it allows the reduction of the presence of chemicals in Exxelia magnetic products, currently, identified by ink marking which requires the use of protective varnish in order to resist the chemical cleaning agents used by our customers. Moreover, it allows a GREEN production with the drastic reduction of consumables (generally chemical) linked to ink marking and thus the need for recycling, for less impact on the environment.         Exxelia is part of an eco-responsible approach with many industrial advantages, namely Indelible marking => optimal traceability (even on the smallest products), permanent and of constant quality. Resistance to corrosion and heat. Resistance to chemical agents => no need to use protective varnish on our markings. No more use of consumables (compared to ink marking).
