GENERAL INFORMATION capacitors. However, the operating temperature is limited to 110°C. Polystyrene (P.S.) The principle features of polystyrene capacitors are low dielectric losses low dielectric absorption, a very good stability over time and a low negative temperature coefficient. These characteristics make it particularly suitable for precision capacitors, “time constant” and “filter” applications. Reconstituted Mica Various composite dielectrics (plastic + paper or reconstituted mica) are used for manufacturing high-voltage capacitors. They are impregnated with solid thermo-setting...

GENERAL INFORMATION GENERAL INFORMATION GÉNÉRALITÉS CAPACITOR PERFORMANCE VERSUS TEMPERATURE COMPORTEMENT DES CONDENSATEURS EN FONCTION DE LA TEMPERATURE The capacitors’ performance versus temperature essentially depends upon the dielectric type. Figure 1 shows ranges of operating temperatures. Important differences affect the laws governing the changes of the main electrical characteristics. They are highlighted by the following curves : Le comportement des condensateurs en fonction de la température dépend essentiellement de la nature du diélectrique. Les gammes de températures...
