21. For aluminum electrolytic capacitors with non-solid electrolyte the ESR generally decreases with increasing frequency and temperature. 22. In 1952 Bell Labs researchers discovered the use manganese dioxide as a solid electrolyte for a sintered tantalum capacitor. 23. Electrolytic capacitors with non-solid electrolytes show a broader aberration over frequency and temperature ranges than polymer capacitors. 24. The dependence of the impedance and ESR at lower temperatures is very low compared with non-solid electrolytes . 25. Aluminum e-caps with non-solid electrolyte have a polarity marking at the cathode ( minus ) side. 26. Tantalum electrolytic capacitors with solid electrolyte are marked at their positive terminal with a bar or a " + ". 27. These first sintered tantalum capacitors used a non-solid electrolyte , which does not fit the concept of solid electronics. 28. Aluminum electrolytic capacitors with non-solid electrolyte are generally called " electrolytic capacitors " or " e-caps ". 29. A solid electrolyte ensures low equivalent series resistance ( ESR ) and a stable electrical behavior over a broad temperature range. 30. This first solid electrolyte manganese dioxide had 10 times better conductivity than all other types of non-solid electrolyte capacitors.
