It is advisable not to use capacitors that have been in the store for an extended period of time. Tantalum capacitors have a long shelf life. The electrical characteristics of these capacitors are not affected significantly when they are stored for a long period of time.
Tantalum capacitors have a long shelf life. The electrical characteristics of these capacitors are not affected significantly when they are stored for a long period of time. Unlike aluminum electrolytic capacitors, tantalum capacitors have higher stability, and their capacitance does not decrease with time.
The electrical characteristics that are affected when these capacitors are stored for a long time without charge are equivalent series resistance (ESR), leakage current, and capacitance. ESR and leakage current increase while capacitance decreases. Nevertheless, the changes are small if these capacitors are stored at room temperature.
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.
Before using a capacitor, it is important to check its receipt time. Some capacitors require reforming after they have been stored for an extended period of time without recharge. To maximize the life of capacitors, they should be stored under conditions specified by the manufacturer.
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.
