Be sure to use fuse for safety.
For acutual usage, Please kindly evaluate and confirm our part mounted in your product,
Especially, Please make sure to confirm whether the load current exceed Max. rated current
by using the current probe.

Please make sure to use quick acting fuse 2A
Capacitance : 47µF Rated voltage : 200V or higher
Ripple current is 0.22Arms above.
Capacitance : 0.1µF∼0.22µF Rated voltage : 200V or higher
Film capacitor or ceramic capacitor. Reduce the noise terminal voltage.
The constant value should be evaluated in the set.
Capacitance : 220µF∼470µF Rated voltage : 25V or higher,
ESR is 0.25Ω max. Ripple current is 0.4Arms above.
Output noise voltage is infulenced.Please evaluate it in the actual set.
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 peak surge current should be 40A or higher.
(Full-wave rectifier can be used in out part.)
Coil for switching regulator. The inductance should be 470µH,
the rated direct current should be 1.0A above.
Otherwise heating or abnormal oscilation occurs.
10Ω∼22Ω 1/4W
Reduce the noise terminal voltage.The constant value should be evaluated
in set.
Varistor must be used. It protects this part from lightning surge and static
electricity.
