capacitor
Use a quick-acting fuse of (1A)
above 250V, 22 to 820µF
Ripple current 0.13Arms or above
above 25V, 100 to 470µF low impedance
ESR : 0.4Ω Max.
Ripple current 0.25Arms or above
Capacitor impedance affects the output ripple voltage.
above 250V, 0.1 to 0.22µF
Use a film or ceramic capacitor
Evaluate under actual operating conditions.
L1: Power Inductor
Inductance : 1.5mH Rating current : above 0.4A
D1: Rectifier diode
In the absolute maximum ratings, the reverse surge voltage should be
400V or above the average rectifier current should be 1A or greater,
and the forward surge current should be 20A or more.
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.
