DEVELOPMENT OF CLOSE TEMPERATURE COEFFICIENT TOLERANCE CERAMIC CAPACITORS FOR TEMPERATURE COMPENSATION.

Abstract

Temperature compensating capacitors were produced having coefficients over a range from P060 to N750 with a tolerance within plus or minus 15 ppm C where this can be reliably measured, and with the probability indicated that closer tolerances may be held for the lower coefficients. Dielectric properties were excellent throughout with low loss and high insulation resistance and dielectric strength. Quality was found to depend on careful control over every stage of manufacture from raw materials to final coating. For the reliability desired, raw material manufacturers specifications should not be naively accepted. Each shipment should be tested completely. Slip viscosity, composition, deflocculation, and milling are critical. Blending must be thorough. (Author)
