Appendix G

Capacitor value according to country

Table 7 indicates the capacitor value for a 30mA average current for typical application case

(nominal capacitor value, nominal RMS line voltage) versus different AC mains and

frequency values used in different countries.

Moreover, the typical and minimal (nominal capacitor value -10%, minimum RMS line

voltage) output DC current capabilities are included for information.
