Be sure to use fuse for safety.
Please verify operation and characteristics in the customer's circuit before actual usage.
Ensure that the load current does not exceed the maximum rating.
External Component Specifications
FUSE: Fuse
C1: Input capacitor
C2: Noise reduction capacitor
Use a quick-acting fuse (2A)
Above 200V, 47 to 220µF
Ripple current 0.22Arms above
Above 200V, 0.1 to 0.22µF
Use a film or ceramic capacitor.
Evaluate under actual operating conditions.
C3: Output capacitor

Ripple current 1Arms or above
Capacitor impedance affects the output ripple voltage.
L1: Power inductor
Inductance : 470µH, Rating current : above1.6A
Select components that do not easily get magnetically saturated
at high temperature.
Above 400V, current : above 3A
Fast recovery diode.
Please note that both the switching and efficiency characteristics
of the module are affected by this diode.
Recommended products : 31DF4 (Nihon Inter)
Use a rectifying diode with a peak reverse voltage of 400V 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.
