Be sure to use fuse for safety.
For actual usage, Please kindly evaluate and confirm our part mounted in your product,
Especially, Please make sure to confirm the load current does not exceed Max. rated current
by using the current probe.

Choose components that do not easily get magnetically saturated in high temperature.
Recommended part : C13FR (MITSUMI)
R1: For noise terminal
voltage reduction resistor
D1: Flywheel diode
D2: Rectifier diode
ZNR: Varistor
Above 600V, current : above 2.0A, Fast recovery diod e
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 the peak reverse voltage of 800V or higher,
the average rectification current of 1A or large and the peak surge current of
20A or large.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.
Be sure to use it to protect this product from thunder surge and the
static electricity.
