1. Product Usage Instructions
1) The selection of capacitors depends on the maximum voltage applied and is affected by current, frequency and the usage environment.
2) Generally, the external packaging of film capacitors uses fire-resistant and flame-retardant materials (such as flame-retardant casings, flame-retardant epoxy, etc.). However, if exposed to continuous high temperatures or flames, the capacitor core may shrink and deform, causing the casing to rupture, or even the core to melt or burn.
2. Product Storage Instructions
1) Do not store in environments with high temperature and high humidity. It is recommended to store under the following conditions:
Temperature: ≤ 35℃
Humidity: ≤ 80% RH, no condensation is allowed.
2) Do not store in environments with corrosive gases, such as sulfides, acids, alkalis, salts, and organic solvents.
3) Without opening the original packaging, the storage time of the product should not exceed 24 months (counted from the date on the packaging or the body of the product).
