1. What is Aluminum Polymer Capacitor?
Aluminum polymer capacitors are electrolytic capacitors that use conductive polymers instead of traditional electrolytes as cathode materials, with lower equivalent series resistance (ESR) and better performance.
-
2. What are the disadvantages of aluminum polymer capacitors?
The disadvantages of aluminum polymer capacitors include high cost, limited available voltage range, and potential performance degradation under prolonged high temperature exposure.
-
3. What are the typical applications of aluminum polymer capacitors?
These capacitors are widely used in devices such as computers, communication equipment, consumer electronics, power modules, DC-DC converters, etc. that require low ESR and high frequency characteristics.
-
4. What is the reliability of aluminum polymer capacitors?
Aluminum polymer capacitors typically have high reliability, especially in long-term use and high-frequency circuits where they perform exceptionally well. Its stability makes it highly favored in many demanding industrial applications.
