These condensers are used in the intermediate circuit applications of power electronics e.g. in conversion technology, where they are increasingly displacing the currently used electrolytic capacitors owing to increasing electrical requirements.
They are designed on the basis of a low-loss polypropylene film & show a higher AC-load carrying capacity at high frequencies as well as low power loss/intrinsic heating than the comparable electrolytic capacitors.
Moreover, they are also characterised by:
- Very high volume capacity
- High rated voltage per component
- Very low loss factor (ESR)
- Very high insulation resistance
- Excellent self-healing properties
- High life expectancy
- Unpoled design
- Special contact-proof connection configurations
