D1: Rectifier diode
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 peak surge current should be 20A or higher.
(Full-wave rectification can be used.)
Coil for switching regulator. The inductance should be 1mH,
the rated direct current should be 0.6A or greater in order to prevent
overheating or abnormal oscillation.
L1: Choke coil
10 to 22Ω 1/4W
Determine the ideal value through actual testing.
R1: Noise reduction
resistor
A varistor is required to protect against lightning surges and
static electricity.
