Abstract
1,244,459. Electrolytic capacitors. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 20 March, 1970 [25 March, 1969], No. 13478/70. Heading H1M. A liquid electrolyte for an electrolytic capacitor consists of 5 to 30% by weight of picric acid and/or an alkali metal picrate, the solvent being a mixture of an alcohol with a dimethyl substituted amide. Preferably, the solution also contains 0À1 to 10% by weight of phosphorous and/or citric acid. Up to 5% of water is tolerable.
