L1: Power inductor
D1: Rectifier diode
Use a quick-acting fuse (1A)
above 450V, 3.3 to 33µF
Ripple current 0.13Arms or greater
above 35V, 100 to 470µF, low impedance
ESR : 0.4Ω Max.
Ripple current 0.25Arms or greater
Capacitor impedance affects the output ripple voltage.
above 450V, 0.1 to 0.22µF
Use a film or ceramic capacitor. Evaluate under actual
operating conditions.
Inductance : 1mH, Rating current: above 400mA
Select components that do not easily get magnetically saturated at
high temperature.
Recommended part : C10-FR 1.0mH(MITSUMI)
Use a rectifying diode with a peak reverse voltage of 800V or higher,
an average rectification current of 1A or larger and a peak surge
current of 20A or larger. When using a large capacitance input capacitor,
select a component that is strong against inrush current during power up.
Full-wave rectification can be used.
