∗1 Max output current should be reduced according to the surrounding temperature.
∗2 The output ripple voltage may vary depending on the capacitance, environment, and location of peripheral components. Especially right
attention has to be paid to aluminum electrolytic capacitor, because ESR changes greatly at the time of the low temperature and output ripple
voltages increase.

Ensure that the load current does not exceed the maximum rating.
External Component Specifications
FUSE: Fuse
C1: Input capacitor
Use a quick-acting fuse (1.0A)
above 250V, 10 to 47µF
C2: Output capacitor
above 25V, 47 to 470µF, Low impedance
ESR:0.42Ω Max.
Ripple current 0.2Arms or greater
Capacitor impedance affects the output ripple voltage.
C3: Noise reduction
capacitor
Above 250V, 0.1 to 0.22µF
Film or ceramic capacitor.
Evaluate under actual operating conditions.
R1: Noise reduction
resistor
10 to 100Ω, 1/4W
Determine the ideal value through actual testing.
D1: Rectifier diode
ZNR: Varistor
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 40A 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.
A varistor is required to protect against lightning surges and static electricity.
