1). Improper selection: Mismatched voltage/frequency (e.g., low-voltage capacitors used in high-voltage scenarios, high-frequency capacitors used in ultra-high-frequency environments);
2). Installation issues: Poor grounding, excessively long pins, and seal failure (due to moisture/dust intrusion);
3). Environmental impacts: High temperatures exceeding the temperature resistance range, and internal breakage caused by severe vibration;
4). Aging and wear: Capacitance attenuation after long-term use, and leakage due to aging of the insulation layer. Learn More
