Aluminum Electrolytic Capacitors Features

Panasonic, one of supplier of all aluminum and tantalum polymer capacitor technologies provide comparison of its technologies as follows:

• OS-CON is a TCNQ salt electrolyte
• Hybrid combine wet and polymer electrolytes
• SP-Cap is a solid polymer chip capacitor
• POSCAP is a tantalum polymer capacitor

The following chart is demonstrating lifetime with temperature comparison of wet vs polymer vs hybrid aluminum capacitors that can be helpful for a specific application selection guide.
