C2: For noise terminal voltage reduction Capacitance : 0.1µF~0.22µF Rated voltage : 200V or higher Film capacitor or ceramic capacitor. Reduce the noise terminal voltage. The constant value should be evaluated in the set. C3: Capacitor for Output voltage smooting Capacitance : 100µF~470µF Rated voltage : 50V or higher, ESR is 0.39Ω 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 400V or higher, the average rectifying current should be 0.5A or higher, and the peak surge current should be 20A or higher. (Full-wave rectifier can be used in our part.) 10Ω~22Ω 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.
