General technical data electronics are made of dielectric - polypropylene film Survey of specific properties of Polyester (polyethylenete- rephtalate) film Temperature coefficient Water absorption (sink for 24 h): Dielectric absorption: Polyester capacitors are used mainly in electronic devices where special characteristics of electrical where wider temperature range is required. Mainly they are used as conjuctive or block capacitors. Polypropylene film Water absorption: Dielectric absorption: Polypropylene capacitors are used mainly in electronic circuits, where following requirements...

rated capacitance Standard tolerances and belonging codes for marking tolerances of rated capacitances are as follow: The narrowest possible tolerance Available tolerances of rated capacitances are stated at type defined for temperature range Temperature coefficient for single type of capacitors is given in maximum direct voltage which temperature between the lower rated temperature. maximum direct voltage which a capacitor at its upper category temperature. Adequate reducing of voltage for temperature range between upper rated temperature and category temperature is given at single types...

At single types of capacitors the data of allowed pulse loading is valuable for unlimited number of pulses (charging and discharging of capacitors) up to rated voltage Un. Minimum resistance in series with capacitor is then: At the pulses of lower voltage than rated voltage the given values of allowed pulse loading are to multiply with the relation factor rated voltage/pulse voltage. If the demanded pulse loading of the capacitor comply with the requests in certain case, the control is needed to be sure that power loss is not exceeded, resp. self-heating is in area of allowed critical cases...

As dielectric high quality polyester film is used, electrodes are of tin or aluminium foil. The winding is extended foil design, terminals are electrically welded to electrodes on frontal side. Such version is little inductive and because of good contacting suitable for pulse loading operation. Typical electrical Variation of dissipation factor (tanS) Iskra Kondenzatorji

Metallized polyester capacitors As a dielectric high quality polyester film with good electrical properties is used. Electrodes of capacitor are vacuum metallized is self-regenerative after break down. The weak point in dielectric because of un-homogene material in some microseconds regenerate with energy of current bow of charged capacitor. In this process metallized layer of aluminium in the area of weak point without any damage of dielectric burns out. The weak point is blameless insulated. So metallized capacitor withstands breakdowns without a permanent short circuit with considering...
