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 the load current does not exceed Max. rated current
by using the current probe.

Capacitance : 33µF to 100µF Rated voltage : 450V or higher
Capacitance : 220µF to 470µF Rated voltage : 35V or higher,
ESR is 0.16 max. Ripple current is 0.58Arms above.
Output noise voltage is infulenced.Please evaluate it in the actual set.
Capacitance : 0.1µF to 0.22µF Rated voltage : 450V or higher
Film capacitor or ceramic capacitor. Reduce the noise terminal voltage.
The constant value should be evaluated in the set.
L : 1mH Allowable current : 1A or higher
Please use the one that is hard to be magnetic saturated even in the high
temperature.
10Ω to 22Ω 1/4W(short time overload guranteed product)
Reduce the noise terminal voltage.please set it,if necessary.
The constant value should be evaluated in set.
In the absolute maximum ratings, the reverse peak voltage should be
600V or higher, the average rectifying current should be 0.5A or higher,
and the peak surge current should be 20A or higher.
(Full-wave rectifier can be used in out part.)
600V/2A
Please select a power transistor with high-speed switching.
Please make sure to radiate by using heat sink.
Please select appropriate size to protect Q1 from thermal run away.
Thermal resistance : 20°C/W or less.
Varistor must be used. It protects this part from lightning surge and static
electricity.
