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 are the typical applications of aluminum polymer capacitors?
These capacitors are widely used in devices such as computers, communication equipment, consumer electronics, power modules, DC-DC converters, etc. that require low ESR and high frequency characteristics.
-
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.
