FUSE: Fuse Please make sure to use quick acting fuse 1A / Please use the fuse resistance for R2.
C1: Capacitor for input Capacitance : 33µF∼820µF Rated voltage : 450V or higher
voltage smoothing Ripple current is 0.13Arms above.
C2: For noise terminal Capacitance : 0.1µF∼0.22µF Rated voltage : 450V or higher
voltage reduction Film capacitor or ceramic capacitor. Reduce the noise terminal voltage.
The constant value should be evaluated in the set.
C3: Capacitor for Output Capacitance : 220µF∼1000µF Rated voltage : 35V or higher,
(15V output) ESR is 0.16Ω max. Ripple current is 0.4Arms above.
Output ripple voltage is influenced. Please evaluate it in the actual se
C4: Capacitor for Output Capacitance : 220µF∼1000µF Rated voltage : 16V or higher,
(5V output) ESR is 0.25Ω max. Ripple current is 0.4Arms above.
Output ripple voltage is influenced. Please evaluate it in the actual set.
L1: Choke coil L : 1mH Allowable current : 600mA or higher.
Please use the one that is hard to be magnetic saturated even in the high temperature.
D1: Rectifier diode In the absolute maximum ratings, the reverse peak voltage should be
800V or higher, the average rectifying current should be 1A or higher,and
the peak surge current should be 40A or higher.
For rush current, to use the large capacity diode for surge current is recommended.
R2: For noise terminal 10Ω∼22Ω 1/4W Reduce the noise terminal voltage.Please set it,if necessary.
The constant value should be evaluated in set.
R1: Rush current limiting Limiting resistance must be used because rush current at powering up is
resistance applied in proportion to the C1 capacitance.Please determine the resistance value after confirming
the rising characteristics of the module at powering up.
ZNR: Varistor Varistor must be used. It protects this part from lightning surge andstatic electricity.
