PERFORMANCE CHARACTERISTICS Polypropylene has a relatively high dielectric strength compared to polycarbonate and polyester films, as shown in Table 2. This property can be translated into fewer "clearings" of dielectric faults, with enhanced prospects for the manufacture of high quality, high performance, capacitors.

The electrical performance characteristics of metallized-polypropylene tubular metal-case capacitors are described in Figures 1 through 5. The low loss and excellent high frequency characteristics of polypropylene capacitors are fairly well known to component engineers and circuit designers. However, these capacitors exhibit additional performance advantages such as extremely high insulation resistance, excellent capacitance stability, and an essentially linear, negative capacitance change as a function of temperature. | |||||||||||||||||||
