Capacitance : 22碌F~390碌F Rated voltage : 200V or higher
Ripple current is 0.13Arms above.
Capacitance : 0.1碌F~0.22碌F 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 : 100碌F~1000碌F Rated voltage : 25V or higher,
ESR is 0.4鈩?max. Ripple current is 0.25Arms above.
Output ripple voltage is infuenced. Please evaluate it in the actual set.
Capacitance : 100碌F~1000碌F Rated voltage : 16V or higher,
ESR is 0.4鈩?max. Ripple current is 0.25Arms above.
Output ripple voltage is infuenced. Please evaluate it in the actual set.
L : 1mH Allowable current : 490mA or higher.
Please use the one that is hard to be magnetic saturated even in the high temperature.
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.
Rush current can be reduced by setting R1, but, to use the large capacity one for surge
current is recommended.(Full-wave rectifier can be used in our part.)
Limiting resistance must be used because rush current at powering up is
applied in proportion to the C1 capacitance.Please determine the resistance value
after confirming the rising characteristics of the module at powering up.
10鈩22鈩?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.
