Polymer Aluminum Electrolytic CapacitorsComparison with various capacitors

Comparison of Capacitor Characteristics

We will compare the characteristics of different types of capacitors, bringing in related data where relevant. Figure 1 is a comparative table of capacitor characteristics. Aluminum electrolytic capacitors (can type) using a conventional electrolyte and tantalum electrolytic capacitors using manganese dioxide (MnO2) are comparatively inexpensive, but they are inferior to polymer capacitors in their frequency characteristics, temperature characteristics, service life, and reliability.

Chip type polymer aluminum electrolytic capacitors have the lowest ESR among all polymer capacitors, which makes them advantageous for ripple absorption applications, etc.
