Tantalum Capacitors Review
Tantalum capacitors are easily mounted onto circuit boards, and give engineering designers the ability to place these components in closely-confined printed circuit board space, as well as utilizing tantalum capacitors'' excellent power dissipation characteristics.
SOLID TANTALUM ELECTROLYTIC CAPACITORS
The ripple capability of solid tantalum electrolytic capacitors is defined by both Equivalent Series Resistance (ESR) and power dissipation due to ripple current. If the capacitor sees a higher than specified amount of ripple current, heat generation within the capacitor will increase eventually causing a
