Be sure to use fuse for safety.
Please verify operation and characteristics in the customer's circuit before actual usage and ensure
that the load current does not exceed 0.6A.
External Component Specifications
FUSE: Fuse
Use a quick-acting fuse (2A)
C1: Input capacitor
Above 200V, 47 to 220µF
Ripple current 0.22Arms or greater
C2: Noise reduction
Above 200V, 0.1 to 0.22µF
capacitor
Use a film or ceramic capacitor. Evaluate under actual operating
conditions.
C3: Output capacitor
Above 50V, 330 to 1000µF, low impedance
ESR : 0.08Ω Max.
Ripple current 1Arms or greater
Capacitor impedance affects the output ripple voltage.
L1: Power inductor
Inductance : 1.0mH, Rating current : above 1.2A
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.
1.0 to 2.2Ω, 1/4W
Determine the ideal value through actual testing.
A varistor is required to protect against lightning surges and static
electricity.
