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 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 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.
