∗1Max 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.

C3: For noise terminal
Above 250V, 0.1 to 0.22µF
voltage reduction capacitor Film capacitor or Ceramic capacitor
Reduce the noise terminal voltage.
The constant value should be evaluated in the product.
R1: For noise terminal
10 to 100Ω, 1/4W
voltage reduction resistor Reduce the noise terminal voltage.
The constant value should be evaluated in the product.
D1: Rectifier diode
Use a rectifying diode with the peak reverse voltage of 400V or higher,
the average rectification current of 1A or larger
and the peak surge current of 40A or larger.
When using an input capacitor of a large capacity,
choose a component that endures the inrush current on power-up.
This product is compatible with full-wave rectification.
