6 FAQs about [Specification of flammable dielectric capacitors]
Are polypropylene FLM capacitors better than electrolytic capacitors?
Polypropylene flm capacitors have much lower ESR to handle the AC ripple without overheating. Film technology advantages over electrolytics are listed below. Two times the voltage capability frees you from series capacitors and voltage balancing resistors. Three times the ripple current capability frees you from needing excess cap to handle ripple.
Can CDE film capacitors be used with pacitors?
pacitors.AC Voltage Operation:Youcan use all CDE film capacitors with either AC or DC vo tages or a combination of the two. The rules for successful application are: 1) don’t exceed the dielec-tric’s voltage capability; 2) keep the capacitor cool,
How reliable are film capacitors?
The most important reliability feature of film capacitors is their self-healing capability, i.e. their abil-ity to clear faults (such as pores or impurities in the film) under the influence of a voltage. The metal coatings, vacuum-deposited directly onto the plastic film, are only 20 50 nm thick.
Which electrolytic capacitors have a lifetime specification?
Polymer, solid tantalum, and solid niobium electrolytic capacitors also have a lifetime specification. However, they do not have a lifetime specification in the non-solid AEC sense. The many types of electrolytic capacitors exhibit different electrical aging behaviors and intrinsic failure modes.
What affects the capacitance of aluminum electrolytic capacitors?
Capacitance depends mainly on the condition of the dielectric in aluminum electrolytic capacitors. Indeed, the capacitance depends on the quality of the etching and the actual surface of the dielectric. Moreover, the phenomenon of self-healing of the dielectric has an influence on the quality of the dielectric and consequently on the capacitance.
How does humidity affect the capacitance of a plastic film capacitor?
The capacitance of a plastic film capacitor will undergo a reversible change of value in relation to any change in the ambient humidity. Depending on the type of capacitor design, both the dielec-tric and the effective air gap between the films will react to changes in the ambient humidity, which will thus affect the measured capacitance.
