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.

FUSE: fuse
C1: Input capacitor
or greater
C2: Output capacitor
or higher.

C3: Noise removal capacitor
L1: Power inductor
film or ceramic capacitor
Evaluate under actual operating conditions.
Inductance : 1.0mH, Rating current:above 0.74A
Select components that do not easily get magnetically saturated at high temperature.
Recommended part : C13FR (MITSUMI)
Determine the ideal value through actual testing.
Use a quick-acting fuse (1.0A)

Above 600V, current : above 2.0A, Fast recovery diode
Please note that both the switching and efficiency characteristics of the module are affected by this diode.
Recommended part : CMF01 (Toshiba)
Use a rectifying diode with a peak reverse voltage of 800V or higher, an average rectification current of 1A or large and a
peak surge current of 20A or large.When using a large capacitance input capacitor, select a component that is strong against
inrush current at power up. Full-wave rectification can be used.
A varistor is required to protect against lightning surges and static electricity.
D2: Rectifier diode
