6 FAQs about [Aluminum electrolytic capacitor accuracy]
Are aluminum electrolytic capacitors a reliable power converter?
Abstract: Aluminum electrolytic capacitors (Al-Cap) are widely used in the DC-links of many power converters. Al-Cap is of low lifetime, which limits the reliability of the power converter. Therefore, it is important to predict the accurate lifetime of the Al-Cap to assist to design a high reliability power converter.
What is the reliability prediction of aluminum electrolytic capacitors?
The reliability prediction of aluminum electrolytic capacitors is generally expressed as a Failure rate λ, abbreviated FIT (Failures In Time). It is a measure of the number of failures per unit hour during the time of constant random failures in the bathtub curve.
What are aluminum electrolytic capacitors?
Aluminum electrolytic capacitors are (usually) polarized electrolytic capacitors whose anode electrode (+) is made of a pure aluminum foil with an etched surface. The aluminum forms a very thin insulating layer of aluminum oxide by anodization that acts as the dielectric of the capacitor.
Can aluminum electrolytic capacitors be charged up to rated voltage?
Aluminum electrolytic capacitors with non-solid electrolytes normally can be charged up to the rated voltage without any current limitation. This property is a result of the limited ion movability in the liquid electrolyte, which slows down the voltage ramp across the dielectric, and the capacitor's ESR.
Can aluminum electrolytic capacitors withstand test conditions?
Most of our aluminum electrolytic capacitors can withstand test conditions imparting peak vibration accelerations of 10 g’s. More specific limits are shown in the specifications for each capacitor series. Frequencies are usually in the range of 10 to 2,000 Hertz. We ofer some series that are specially constructed to withstand testing up to 80 g’s.
What is a typical temperature range for aluminum electrolytic capacitors?
The typical temperature range for aluminum electrolytic capacitors is –40 oC to 85 oC or 105 oC. Capacitance varies about +5% –40% over the range with the capacitance loss all at cold temperatures. Capacitors rated –55 oC generally only have –10% to –20% capacitance loss at –40 oC.
