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. How do aluminum polymer capacitors perform in high temperature environments?
These capacitors have good high-temperature stability and can typically operate in environments ranging from 85 ° C to 105 ° C, exhibiting excellent performance at high temperatures, especially compared to traditional capacitors with liquid electrolytes.
-
4. How to choose the capacity and voltage of aluminum polymer capacitors?
The selection of appropriate capacitor capacity and voltage depends on specific circuit design requirements. Usually, the capacity depends on the required filtering performance, and the voltage selection should ensure that it is 20% -30% higher than the actual operating voltage.
