Packaging and Transportation

Packaging: Capacitors are packed in plastic bags in multiples of 100, with a certificate of conformity inside. Bags are then placed in cartons. Tape and reel packaging is available upon customer request.
Labeling: Package labels include material number, supplier trademark, product model, nominal capacitance, tolerance, rated voltage, batch number/production date, quantity, inspector, and packer.
Transportation: Packaging is suitable for all modes of transport but should be protected from direct rain, snow, and mechanical damage.
Storage Conditions: Temperature below 35, relative humidity below 65%, free from corrosive substances (acids, alkalis, etc.).
Shelf Life: Recommended to use within 1 year to prevent lead oxidation.
