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 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 frequency range are aluminum polymer capacitors suitable for?
Aluminum polymer capacitors are typically suitable for high-frequency applications, with a frequency range of several hundred kHz to MHz, making them ideal for use in high-frequency circuits.
-
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.
