Eclipse NanoMed, LLC utilizes revolutionary, leading edge dielectric materials developed by its parent company Eclipse Design & Material, Inc.. These dielectrics, in their simplest form, can be classified as either Class I, COG or Class II materials, as defined by EIA-198, but their actual performance characteristics far exceed those achieved by the alternative, more traditional dielectrics. Intended for multiple operating temperature ranges from -55°C to as high as +300°C for extremely harsh conditions, they are capable of achieving exceptionally high levels of volumetric efficiency, dielectric breakdown, and insulation resistance, while maintaining predictable performance characteristics related to variations in temperature and applied voltage.

The Eclipse COG material is characterized by an extremely low dissipation factor (DF) or inversely, by an extremely high Quality factor (Q). At measurable DF levels well below 0.00005 (0.005%) at +25°C, Q factor levels of between 20,000 and 40,000 are achievable, making these best in class designs highly advantageous for RF and microwave applications. Changes in capacitance associated with higher temperature levels comply with COG limits of ±30 PPM / °C and DF levels remain relatively low at higher temperatures maintaining levels of 0.08%, 0.5% and 1.0% maximum at +200°C, +250°C and +300°C respectively.

The Eclipse Class II dielectric material can be classified as an X7R dielectric for operating temperatures between -55 and +125°C. Variations in capacitance due to increases in temperature and applied voltage bias beyond this X7R limit are predictable and limited to maximum reductions of -72%, -83% and -86% at rated voltage and +200°C, +250°C and +300°C respectively. Unlike other readily available X7R or high temperature Class II dielectrics, the materials developed by Eclipse achieve a much higher nominal dielectric constant (K) of 5000 at +25°C and as such are able to attain a very high level of capacitance per unit volume. These high CV levels are very critical in those applications like aerospace flight systems and implantable medical devices where limiting mass and size is a critical component of any design. In addition, the high CV capacitance characteristic of these devices allow us to achieve energy levels approaching 2.5 joules in a single 4.7 ìF, 13560 chip capacitor rated for 1Kvdc at +25°C. Also available in multiple chip cap assemblies, these high energy density capacitors are highly desirable for fusing applications in military or down-hole applications.

Another major concern for operation at elevated temperature is the level of Insulation Resistance (IR) or leakage current that the capacitor can maintain. Both Eclipse NanoMed dielectric material classifications can achieve IR levels at +200°C that are in line with what is typically defined for +125°C operation. For higher temperature designs rated at +250°C and +300°C, IR minimums are reduced to 5 . – F or 500 M. and 0.1 . – F or 10 M. respectively. Competitive benchmarks are very limited or unavailable at +300°C because there are no other qualified suppliers, but where information is available, these limits represent as much as a 5X to 100X improvement over those published by our competition.

For leaded capacitor assemblies intended for high temperature applications, Eclipse NanoMed has developed a proprietary lead attachment process that has achieved operational success at temperatures as high as +600°C. This approach does not use solder as the attachment method and has achieved extremely high pull strength results in excess of 12 lbs. Carried to the point of failure, the mechanism in the majority of cases does not involve a compromise in the attachment area but tends instead to be characterized by lead rupture.

The reality of the situation we are faced with today is that for future down-hole, geothermal, aerospace and automotive applications, there is an immediate and pressing need for capacitors capable of meeting the extreme operating conditions associated with temperatures up to and exceeding +300°C. The other truth is that Eclipse NanoMed, LLC is the only supplier of mature product that can currently and effectively support these demands.

Eclipse NanoMed's product offering includes:

• Application specific MLCC ceramic capacitors
• Leaded capacitor assemblies and modules
• 0805-13560 case sizes
• Commercial temp ranges to +300 degrees C
