Permissible ripple current is 0.13Arms or higher
C2: Output capacitor
Rated voltage 35V or higher, 100 to 470µF
Low impedance type
Impedance is 0.4Ω max at high frequencies.
Evaluate under actual operating conditions.
Rated voltage 400V or higher 0.1 to 0.22µF
Film or ceramic capacitor
Evaluate under actual operating conditions.
Ripple current 0.25Arms or greater.
Capacitor impedance affects the output ripple voltage.
D1: Rectifier diode
Inductance : 1.5mH
Permissible current value 300mA or higher
A reverse surge voltage 800V or higher
An average rectifying current 0.5A or higher
