Product Details

Vishay 021 ASM Series Aluminium Electrolytic Capacitors

021 ASM electrolytic capacitors from Vishay are constructed from a cylindrical aluminium case insulated with a blue sleeve. These electrolytic capacitors feature a non-solid electrolyte and are charge and discharge proof. 021 ASM electrolytic capacitors have a long lifespan between 2500 hours and 8000 hours at +85°C.

Product Features:

• Polarised • Axial leads
• Miniaturised
• High CV-product per unit volume


These electrolytic capacitors are suitable for general purpose usage and can be used in industrial, automotive and audio-video applications. They are ideal for coupling and decoupling, filters, smoothing and buffering. The miniature size of the 021 series enables use on boards with a low mounting height. Other suitable applications include mobile and portable equipment with a small size and low mass.
