Be sure to use fuse for safety.
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: Fuse
Use a quick-acting fuse of 0.5A
C1: Input smoothing
capacitor
Capacitance : 3.3 to 22µF Rated voltage : 450V or higher
Ripple current is 0.13Arms or greater.
C2: Noise reduction
capacitor
C3: Output smoothing
capacitor
D1: Rectifier diode
Capacitance : 0.1 to 0.22µF Rated voltage : 450V or higher
Use a film or ceramic capacitor. Evaluate under actual
operating conditions.
Capacitance : 100 to 470µF Rated voltage : 16V or higher,
ESR is 0.4Ω max. Ripple current is 0.15Arms or greater.
Evaluate under actual operating conditions.
In the absolute maximum ratings, the reverse peak voltage should be
800V 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.)
R1: Noise reduction
resistor
ZNR: Varistor
10 to 22Ω 1/4W
Determine the ideal value through actual testing.
A varistor is required to protect against lightning surges and
static electricity.
