In standard schematics, the symbol for polarized capacitor features a straight line for the positive (+) and a curved or shaded line for the negative (-). On physical components, the negative lead is typically shorter, and the casing often has a striped band indicating the negative side. Our components are clearly marked to prevent assembly errors.
All our products comply with international standards including RoHS, CE, UL, FCC, and ISO 9001. We provide full documentation for customs clearance in the USA, EU, and other major markets.
