Tantalum capacitor

Materials, production and. Applications using tantalum capacitors take advantage of their low leakage current, high capacity and long term stability and reliability. For example, they are used in sample and hold circuits which rely on low leakage current to achieve long hold duration. Tantalum capacitors are a subtype of electrolytic capacitors.

They are made of tantalum metal which acts as an anode, covered by a layer of oxide which acts as the dielectric, surrounded by a conductive cathode. The use of tantalum allows for a very thin dielectric layer.

Please view our large selection of. Capacitors – Tantalum Capacitors are in stock at DigiKey. They are ideal where high capacitance but low current is required. Nov Tantalum (Ta) capacitors and multilayer ceramic capacitors (MLCCs) are two widely accepted capacitor technologies that can be employed in a. Tantalum powder is used in capacitors to allow for a very thin dielectric layer, providing high capacitance values in smaller case sizes.

This type of capacitor is Polarized in nature. In this capacitor a. Higher performance polymer cathode tantalum capacitors are also supported with low ESR and high ripple current ratings for power applications.
