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
C1: Input capacitor
C2: Noise removal capacitor
Use a quick-acting fuse (0.5A)
Above 200V, 3.3 to 22µF
Ripple current 0.13Arms or above.
Above 200V, 0.1 to 0.22µF
Film or ceramic capacitor
Reduce the noise terminal voltage.
The value should be verified under actual conditions.
Above 25V, 100 to 470µF, low impedance
ESR : 0.39Ω Max.
Ripple current 0.1Arms or above
Capacitor impedance affects the output ripple voltage.
Resistance : 10 to 22Ω, Power : More than 1/4Ω
Use a rectifying diode with a peak reverse voltage of 400V or higher,
an average rectification current of 0.5A or larger and a large capacity input
capacitor, peak surge current of 20A or larger. When using a large capacity
input capacitor, choose a component that is strong against inrush current
during startup.
This product is compatible with full-wave rectification.
A varistor must be used to protect against lightning surges and static
electricity.
