Be sure to evaluate it under the cindition that it is mounted by your product.
Especially, Confirm whether output current never exceeds a maximum standard
with current probe.
Outside part
F1: FUSE
Use a fuse for safety.
C1: Input capacitor
Rated voltage : More than 50V
Capacity : more than 100µF, low impedance type
Rated ripple current : More than 0.2Arms
C2: Output capacitor
Rated voltage : More than 10V
Capacity : 220 to 680µF, low impedance type
Rated ripple current : More than 0.2Arms
Evaluate it with the actual opportunity because
it influences an output ripple 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
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.
