External Component Specifications
Above 200V, 3.3 to 22µF
Ripple current 0.13Arms or above.
C2: Noise removal capacitor
C3: Output capacitor
Load Regulation
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.
R1: Noise removal resistor
Resistance : 10 to 22Ω, Power : More than 1/4Ω
D1: Rectifier diode
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.
ZNR: Varistor
A varistor must be used to protect against lightning surges and static
electricity.
