Surface Mount Solid Polymer Aluminum Capacitors

A768 125°C

Stability of ESR across Frequency Range

Due to a solid polymer electrolyte, the ESR curve of a solid polymer aluminum capacitor, is lower and more stable than that

of a standard electrolytic capacitor.

High Resistance to Ripple Current

As a result of a lower ESR, solid polymer aluminum capacitors are able to withstand higher ripple currents during

normal operation.
