Capacitor Polarity: What You Need to Know
Polarized capacitors such as electrolytic and tantalum capacitors possess a designated direction of charge and frequently appear in power supply decoupling, audio systems, or timing circuits. In contrast to these components, non-polarized varieties such as ceramic and film ones do not need an orientation for operating correctly; making them ideal for high-frequency …
4.7 µF Tantalum Capacitors
Tantalum capacitors have an anode electrode (+) made of tantalum metal, electrolyte that acts as the cathode, and a thin insulating layer of tantalum oxide that acts as the dielectric. Tantalum capacitors have high capacitance-voltage (CV) product per unit volume at low weights and are known for high reliability.
