Ripple current 1Arms or greater
Capacitor impedance affects effects the output ripple voltage
Inductance : 330µH, Rating current : above 1.6A
Select components that do not easily get magnetically saturated
at high temperature.
Above 400V, current : above 3A
Fast recovery diode
Please note that both the switching and efficiency characteristics of the
module are affected by this diode.
Recommended products : 31DF4 (Nihon Inter) or RU30 (Sanken)
Use a rectifying diode with a peak reverse voltage of 400V or higher,
an average rectification current of 1A or larger and a peak surge current of
20A or larger. When using a large capacitance input capacitor, select a
component that is strong against inrush current during power up.
Full-wave rectification can be used.
1 to 2.2Ω, 1/4W
Reduce the noise terminal voltage.
Determine the ideal value through actual testing.
A varistor is required to protect against lightning surges and static
electricity.
