Ensure that the load current does not exceed the maximum rating. External Component Specifications FUSE: Fuse C1: Input smoothing capacitor C2: Output smoothing capacitor Use a quick-acting fuse of 1.0A Capacitance : 3.3 to 33µF Rated voltage : 250V or higher Capacitance : 47 to 470µF Rated voltage : 16V or higher, low impedance Impedance is 0.42Ω max at high frequencies Ripple current is 0.2Arms or above. Capacitor impedance affects the output ripple voltage. Capacitance : 0.1 to 0.22µF Rated voltage : 250V or higher Use a film or ceramic capacitor. Evaluate under actual operating conditions. In the absolute maximum ratings, the reverse peak voltage should be 400V or higher, the average rectifying current should be 1A or higher, and the forward surge current should be 40A or higher. 10 to 22Ω 1/4W Determine the ideal value through actual testing. A varistor is required to protect against lightning surges and static electricity.
