Please verify operation and characteristics in the customer's circuit before actual usage.
Ensure that the load current does not exceed the maximum rating.
External Component Specifications
FUSE : Use a quick-acting fuse of 0.5A.
ZNR : Varistor
D1: Rectifier diode
C3: Input smoothing
capacitor
A varistor is required to protect against lightning surges and static electricity.
In the absolute maximum ratings, the reverse peak voltage should be
400V or higher, the average rectifying current should be 0.5A or higher,
and the peak surge current should be 20A or higher.
(Full-wave rectification can be used.)
Rated voltage : 200V or higher. Capacitance : 33 to 330µF
FL1: Noise reduction filter Use a line filter if necessary.
C1,2,4 : Noise reduction
capacitors
Capacitance (C1,C2) : 0.1 to 0.22µF, (C4) : 4700pF
Rated voltage : 200V or higher. Film or ceramic capacitor.
Evaluate under actual operating conditions.
C5: Output smoothing
capacitor
Capacitance : 470 to 1000µF Rated voltage : 25V or higher,
ESR is 0.16Ω max. Ripple current is 0.58Arms or greater
Low impedance type.
Evaluate under actual operating conditions.
