Capacitor Selection Checklist: Important parameters to consider

1. Capacitance and its tolerance at@ 25 degrees centigrade
2. Working Voltage DC or AC
3. ACfrequency (ie: 60hz)
4. Maximum operating temperature
5. Physical size and weight limitations
6. Application

For high frequency, high current applications:

7. Maximum AC current
8. AC frequency of operation
9. Peak AC Voltage

Pulse capacitor requirements:

10. Charge Voltage
11. Discharge current
12. Repetition Rate
13. Load Resistance
14. Voltage Reversal
15. Maximum capacitor inductance
