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.
External components setting
FUSE: Fuse
C1: Capacitor for input
voltage smoothing
C2: For noise terminal
voltage reduction
C3: Capacitor for Output
voltage smooting
D1: Rectifier diode
L1: Choke coil
R1: For noise terminal
voltage reduction
ZNR: Varistor
Please make sure to use quick acting fuse 1A
Capacitance : 10~100µF Rated voltage : 450V or higher
Ripple current is 0.13Arms above.
Capacitance : 0.1µF~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.
Capacitance : 100µF~2200µF Rated voltage : 25V or higher,
ESR is 0.4Ω max. Ripple current is 0.25Arms above.
Output noise voltage is infulenced.Please evaluate it in the actual set.
In the absolute maximum ratings, the reverse peak voltage should be
800V 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.)
Coil for switching regulator. The inductance should be 1.5mH,
the rated direct current should be 0.3A above.
Otherwise heating or abnormal oscilation occurs.
10Ω~22Ω 1/4W
Reduce the noise terminal voltage.Please set it,if necessary.
The constant value should be evaluated in set.
Varistor must be used. It protects this part from lightning surge and static
electricity.
