∗1 Maximum output current varies depending on ambient temperature ; please refer to derating curve.
∗2 The output ripple voltage may vary depending on the capacitance, environment, and location of peripheral components. Particular
attention must be paid to aluminum electrolytic capacitor, because ESR changes greatly at the time of the low temperature and output ripple
voltages increase.

FUSE: Fuse
Use a quick-acting fuse of 1.0A
C1: Input smoothing
capacitor
Capacitance : 3.3 to 33µF
Rated voltage : 250V or higher
C2: Output smoothing
capacitor
Capacitance : 47 to 470µF
Rated voltage : 16V or higher, low impedance
Impedance is 0.42Ω max at high frequencies
Ripple current is 0.2Arms or above.
Capacitor impedance affects the output ripple voltage.
C3: Noise reduction
capacitor
Capacitance : 0.1 to 0.22µF Rated voltage : 250V or higher
Use a film or ceramic capacitor. Evaluate under actual operating
conditions.
D1: Rectifier diode
In the absolute maximum ratings, the reverse peak voltage should be
400V or higher, the average rectifying current should be 1A or higher,
and the forward surge current should be 40A or higher.
R1: Noise reduction
resistor
10 to 22Ω 1/4W
Determine the ideal value through actual testing.
ZNR: Varistor
A varistor is required to protect against lightning surges and static
electricity.
