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. 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.
