Abstract:

Research was concerned with the design and production of preliminary, prototype, and finalgrade capacitor microelements of various types. General-purpose precision, temperature-compensating ceramic capacitors and tantalum electrolytic capacitors were req ired to meet specific micro-module needs, including ranges f values, working voltages, reliability characteristics, AND OTHER SPECIFICATIONS APPLICABLE TO CONVENTIONAL CAPACITORS. Ceramic capacitors of singlelayer and multilayered thin-film ceramic dielectrics were produced. Monolithic structures of layered thin film were employed to reduce thickness and achieve higher capacitance ranges. Nominal capacitance values from approximately 5 micromicrofarads to 0.005 microfarads including both general-purpose and precision types, were obtained in 0.010-inch-thick layer construction. For the multilayer ceramic capacitors nominal capacitance values ranging from approximately 30 micromicrofarads to 0. micro arads were obtained in general-purpose and precision types. Over 3800 final-grade elements were fabricated and tested. More than 2000 tantalum-electrolytic capacitor microelements were also produced. Author
