2. Can I use an electrolytic capacitor for AC circuits? No, they are polarized and designed for DC circuits. For AC, use non-polarized or film capacitors.
3. What does the voltage rating mean? It is the maximum DC voltage the capacitor can withstand continuously. Always use a rating 1.5x to 2x the circuit voltage.
4. How do I read the capacitance value? Usually in microfarads (µF). For example, 100 µF = 100,000 nF. Some use a three-digit code (e.g., 107 = 100 µF).
5. What is ESR and why is it important? Equivalent Series Resistance (ESR) is the internal resistance. Low ESR is critical for high-frequency and high-ripple current applications.
6. Can I replace a 16V capacitor with a 25V one? Yes, as long as the capacitance is the same or higher. Higher voltage rating is safe but may be larger.
7. Why do electrolytic capacitors fail? Common causes include high temperature, voltage spikes, reverse polarity, and aging of the electrolyte.
8. What is the difference between aluminum and tantalum? Tantalum has higher stability, lower leakage, and longer life but is more expensive and sensitive to voltage spikes.
9. How should I store electrolytic capacitors? In a cool, dry place below 40°C. They have a shelf life of 2-3 years; reform them before use if stored longer.
10. What is a snap-in capacitor? A type of aluminum electrolytic with snap-in terminals for easy mounting on PCBs, used in power supplies.
