doubt fails smd capacitors

[gamer87]

Ceramic smd capacitors, polyester smd capacitors mounted on a PCB electronic circuit and stored for long periods of time without being energized without use, suffer from the same problem as aluminum electrolytic capacitors, losing capacitance, high leakage current...?

Ceramic and polyester capacitors generally do not suffer from the same problems as aluminum electrolytic capacitors when they are stored for long periods of time without being energized. These types of capacitors are generally very stable and do not exhibit significant changes in capacitance or leakage current over time.

However, it is important to note that all capacitors can be affected by various factors such as temperature, humidity, and voltage, which can cause changes in their electrical characteristics. In general, it is recommended to store capacitors in a dry, cool place and to handle them carefully to avoid damage. If a capacitor is going to be stored for an extended period of time, it is also a good idea to keep it in its original packaging to protect it from any potential damage.
