Above 250V, 0.1 to 0.22µF
Use a film or ceramic capacitor.
Evaluate under actual conditions.
L1: Power inductor
Inductance : 1mH, Rating current : above 600mA
Choose components that do not easily get magnetically saturated at
high temperature.
D1: Rectifier diode
Use a rectifying diode with a peak reverse voltage of 400V or higher,
an average rectification current of 0.5A or larger and a peak surge
current of 20A or larger. When using a large capacitance input capacitor
select a component strong against inrush current during power up.
Full-wave rectification can be used.
R1: Noise reduction
resistor
10 to 22Ω, 1/4W
Determine the ideal value through actual testing.
ZNR: Varistor
A varistor must be used to protect against lightning surges and static
electricity.
