The shelf life depends on storage conditions. Temperature, atmospheric pressure and humidity. Electrolytic capacitors are most susceptible to high temperatures. The current aluminum electrolytic capacitors shelf life is approximately 2 years. If storing these capacitors at a high temperature rating, it can degrade the sealing material.
Subjecting capacitors to harsh conditions can significantly affect their electrical properties, or even damage them completely. The effect of environmental factors on the shelf life of capacitors varies depending on the chemical composition and construction of a capacitor.
The storage capability of the capacitor is defined by the so-called shelf life. Please see Table 1 for information that is more detailed. The shelf life simulates the aging of the capacitor under the influence of temperature without an electrical load (voltage, current).
Ceramic capacitors should be stored at temperature and humidity conditions specified by the manufacturer. Before using a capacitor, you should check the recommended shelf life, date of receipt, and inspect terminations. For most capacitors, the shelf life is significantly determined by storage conditions.
The shelf life of ceramic capacitors is greatly determined by method of packaging and storage conditions. Unlike aluminum electrolytic capacitors, the dielectric material of multilayer ceramic capacitors (MLCCs) does not exhibit failures when the capacitor is stored for a short period of time.
There is also a guideline from the ZVEI on the long-term storage capability of components: During storage of an aluminum electrolytic capacitor, two different effects can adversely affect the blocking (insulation) capability of the capacitor, oxide degeneration and post-impregnation effects.
Capacitors can be arranged in two simple and common types of connections, known as series and parallel, for which we can easily calculate the total capacitance. These two basic …
A capacitor can store electric energy. It depends on the load how fast a capacitor discharges when connected to that load. (T = R * C) The voltage rating just specifies …
