Capacitor Mounting Precautions: Avoid excessive mechanical or thermal shock during installation to prevent electrical characteristic deterioration or short circuits. Do not reuse dropped or previously installed capacitors. Do not process or bend terminals after installation. Avoid direct contact with leads to prevent contamination affecting solderability.

Circuit Board Cleaning: Remove flux, acids, and alkalis quickly. Cleaning temperature should be below 50, with total immersion time (ultrasonic, steam) under 5 minutes.

Environment Precautions: Do not use in environments with direct contact with water, brine, oil, direct sunlight, high temperature/humidity with condensation, reactive gases, acids/alkalis, high-frequency wave induction, excessive vibration, or shock.
