1. What is Aluminum Polymer Capacitor?
Aluminum polymer capacitors are electrolytic capacitors that use conductive polymers instead of traditional electrolytes as cathode materials, with lower equivalent series resistance (ESR) and better performance.
-
2. 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.
-
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 do aluminum polymer capacitors perform in high temperature environments?
These capacitors have good high-temperature stability and can typically operate in environments ranging from 85 ° C to 105 ° C, exhibiting excellent performance at high temperatures, especially compared to traditional capacitors with liquid electrolytes.
