Please verify operation and characteristics in the customer's circuit before actual usage. Ensure that the load current does not exceed the maximum rating. External Component Specifications FUSE: Fuse C1: Input smoothing capacitor C2: Noise reduction resistor C3: Output smoothing capacitor D1: Rectifier diode Use a quick-acting fuse of 0.5A Capacitance : 3.3 to 22µF Rated voltage : 450V or higher Ripple current is 0.13Arms or greater. Capacitance : 0.1 to 0.22µF Rated voltage : 400V or higher Use a film or ceramic capacitor. Evaluate under actual operating conditions. Capacitance : 100 to 470µF Rated voltage : 25V or higher, ESR is 0.39Ω max. Ripple current is 0.1Arms or higher. Evaluate under actual operating conditions. 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 or higher. (Full-wave rectification can be used.) 10 to 22Ω 1/4W Determine the ideal value through actual testing. A varistor is required to protect against lightning surges and static electricity.
