C4: For noise terminal voltage Above 600V, 0.1 to 0.22µF
reduction capacitor
Film capacitor or Ceramic capacitor
Reduce the noise terminal voltage.
The constant value should be evaluated in the product.
L1: Power inductor
Inductance:1.0mH, Rating current: above 0.74A
Choose components that do not easily get magnetically saturated in high temperature.
Recommended part : C13-FR 1.0mH (MITSUMI)
D1: Flywheel diode
Above 1000V, current: above 1.0A
Fast recovery diode
Please note that both the switching and efficiency characteristics of the
module are affected by this diode.
Recommended products: UF4007 (VISHAY)
D2: Rectifier diode
Use a rectifying diode with the peak reverse voltage of 1kV or higher, the
average rectification current of 1A or larger and the peak surge current of
20A or larger. When using an input capacitor of a large capacity, choose a
component that endures the inrush current on power-up.
This product is compatible with full-wave rectification.
R1: For noise terminal voltage 10 to 22Ω, 1W
Reduce the noise terminal voltage.

Products listed in this document are no antiradiation design.
The products listed in this document are designed to be used with ordinary electronic equipment or devices
(such as audio visual equipment, office-automation equipment, communications devices, electrical
appliances and electronic toys).
Should you intend to use these products with equipment or devices which require an extremely high level
of reliability and the malfunction of which would directly endanger human life (such as medical
instruments, transportation equipment, aerospace machinery, nuclear-reactor controllers, fuel controllers
and other safety devices), please be sure to consult with our sales representative in advance.
It is our top priority to supply products with the utmost quality and reliability. However, there is always a chance
of failure due to unexpected factors. Therefore, please take into account the derating characteristics and allow
for sufficient safety features, such as extra margin, anti-flammability, and fail-safe measures when designing in
order to prevent possible accidents that may result in bodily harm or fire caused by component failure. ROHM
