Be sure to use fuse for safety.

For acutual usage, Please kindly evaluate and confirm our part mounted in your product, Especially, Please make sure to confirm whether the load current exceed Max. rated current by using the current probe. External components setting C1: Capacitor for input voltage smoothing C2: For noise terminal voltage reduction C3: Capacitor for Output voltage smooting D1: Rectifier diode Capacitance : 3.3uF to 22uF Rated voltage : 450V or higher Ripple current is 0.13Arms above. Capacitance : 0.1uF to 0.22uF Rated voltage : 400V or higher Film capacitor or ceramic capacitor. Reduce the noise terminal voltage. The constant value should be evaluated in the set. Capacitance : 100uF to 470uF Rated voltage : 25V or higher, ESR is 0.39 max. Ripple current is 0.1Arms above. Output noise voltage is influenced.Please evaluate it in the actual set. In the absolute maximum ratings, the reverse peak voltage should be 800V or higher, the average rectifying current should be 0.5A or higher, and the peak surge current should be 20A o
r higher. (Full-wave rectifier can be used in out part.) 10 to 22 1/4W Reduce the noise terminal voltage.The constant value should be evaluated in set. Varistor must be used. It protects this part from lightning surge and static electricity.
