Panasonic ACOM Foil Division: 4 November 1996
Two new aluminum foils are under development for production at Panasonic's American Components division in Knoxville, Tennessee. One is a 700 V formation process that allows 500+ WV capacitor designs, assuming typical 85°C deratings are employed. This process is at the "semi-production" phase. The other formation process creates an amorphous oxide suitable for high discharge capacitor applications such as photoflash units and strobe lights. This process is in the developmental stage.

Aircraft Electroshock Therapy: 21 October 1996
A new market opportunity may be developing for large can screw terminal capacitors to be used in 10kV pulse de-icing circuits for aircraft. Ice can be removed from aircraft surfaces by applying an energy pulse of 400J/ft². Visit FaradNet often to get the details as this market develops.

Boundary Technologies, Inc.: 21 October 1996
BTI electrolytes are being sold in Asia by Suzuki Techno-Commercial Corp. Bob Alwitt, BTI president, is well known in the electrolytic capacitor industry for his contract R&D work. BTI received two patents for having developed the technology to create high voltage butyrolactone-based electrolytes. STCC is an ex/im specialist for all aspects of the capacitor trade.

Cornell-Dubilier: 21 October 1996
CDE is working on standard catalog ratings for their range of photoflash and strobe designs. CDE intends to have a product bulletin by January 1, 1997.

MHDielectrics-vs-NKK: David-vs-Goliath?: 21 October 1996
NKK readies improved impregnation high density kraft spacer papers to compete with MHD kraft-polypropylene KP grades. Samples available in early 1997 with full scale introduction in the summer of 1997. See also Boyd Converting.

Nippon Kodoshi Corp.: 21 October 1996
NKK has been busy developing products to run on the new triplex-capable machine installed at their Aki, Japan plant last fall. The first product off the line is a low density (0.3 g/cc) Manila Long Fiber triplex suitable for low ESR butyrolactone-based electrolytes. The triplex structure is said to minimize the risk of short circuits. See also Boyd Converting.

Universal Products, Inc.: 21 October 1996
UPI has spare capacity on their automated state-of-the-art snap-in cover machine, which is of their own design. UPI has also developed a large can screw terminal cover based on the snap-in cover technology. The cover has been qualified to 105 degC with glycol electrolytes. It's a sure bet to be a winner!
