Capacitance : 47µF to 470µF
Rated voltage : 16V or higher, Low impedance part
Impedance is 0.42Ω max at High frequency range.
Ripple current is 0.2Arms above.
Impedance of capacitor affects the output ripple voltage.
C3: For noise terminal
voltage reduction
Capacitance : 0.1µF to 0.22µF Rated voltage : 250V or higher
Film capacitor or ceramic capacitor. Reduce the noise terminal voltage.
The constant value should be evaluated in the set.
D1: Rectifier diode
In the absolute maximum ratings, the reverse peak voltage should be
400V or higher, the average rectifying current should be 1A or higher,
and the forward surge current should be 40A or higher.
R1: For noise terminal
voltage reduction
10Ω to 22Ω 1/4W
Reduce the noise terminal voltage.
The constant value should be evaluated in set.
ZNR: Varistor
Varistor must be used. It protects this part from lightning surge and static
electricity.

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
cannot be held responsible for any damages arising from the use of the products under conditions out of the
range of the specifications or due to non-compliance with the NOTES specified in this catalog.
