Above 200V, 22 to 100µF
Ripple current 0.13Arms or above.
C2: Noise reduction capacitor
Above 200V, 0.1 to 0.22µF
Use a film or ceramic capacitor.
Evaluate under actual conditions.
C3: Output capacitor
L1: Power inductor
D1: Rectifier diode
R1: Noise reduction resistor
Above 25V, 100 to 470µF low impedance
ESR : 0.25Ω Max.
Ripple current 0.4Arms or above.
Capacitor impedance affects the output ripple voltage.
Inductance : 1mH Rating current : 420mA above
Choose components that do not easily get magnetically saturated at
high temperature.
Use a rectifying diode with a peak reverse voltage of 400V or higher,
an average rectification current of 0.5A or larger and a peak surge
current of 20A or larger.
Full-wave rectification can be used.
