1. What is the difference between aluminum polymer capacitors and traditional aluminum electrolytic capacitors?
Aluminum polymer capacitors have lower ESR, longer lifespan, high temperature resistance, and high-frequency characteristics compared to traditional aluminum electrolytic capacitors, but the cost is usually higher and their voltage range is lower.
-
2. What are the advantages of aluminum polymer capacitors?
They have low ESR, good high-frequency performance, high ripple current handling capability, long lifespan, and stable temperature characteristics, making them particularly suitable for power filtering and voltage stabilization applications.
-
3. 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.
-
4. How long is the lifespan of aluminum polymer capacitors?
Compared to traditional electrolytic capacitors, aluminum polymer capacitors have a longer lifespan, typically reaching thousands or even longer, depending on the application environment and working conditions.
