4 FAQs about [The role of non-hermetic capacitors]
Do electrolytic capacitors degrade if not used?
So, they degrade if not used. When the material deteriorates, the electrolyte dissipates, changing the properties of the capacitor values. Regular maintenance, repair, or swapping of electrolytic capacitors should be scheduled to prevent electrolytic capacitor degeneration in essential circuits.
What is the shelf life of aluminum electrolytic capacitors?
The current shelf life of aluminum electrolytic capacitors is about 2 years. When these capacitors are stored at high temperatures, the sealing material can fail. So, they degrade if not used. When the material deteriorates, the electrolyte dissipates, changing the properties of the capacitor values.
What causes electrolytic capacitor degeneration and failure?
The fundamental mechanism that causes electrolytic capacitor degeneration and failure is the steady evaporation of the electrolyte over time. This is exacerbated at higher temperatures. As a result, capacitance is reduced and effective series resistance (ESR) is increased.
Why do capacitors have low insulating resistance?
The insulating resistance of a capacitor reduces as its temperature rises. This is because electron activity has increased. Moisture trapped in the windings, extended exposure to extreme humidity, or moisture trapped during the manufacturing process can all cause low insulation resistance.
