C1: Capacitor for input
voltage smoothing
Capacitance : 22 to 100μF Rated voltage : 200V or higher
Ripple current is 0.13Arms above.
C2: For noise terminal
voltage reduction
Capacitance : 0.1 to 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.
C3: Capacitor for Output
voltage smoothing
Capacitance : 100 to 470μF Rated voltage : 25V or higher,
ESR is 0.25Ω max. Ripple current is 0.4Arms above.
Output noise voltage is influenced. Please evaluate it in the actual set.
D1: Rectifier diode
In the absolute maximum ratings, the reverse peak voltage should be
400V 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 our part.)
L1: Choke coil
Coil for switching regulator. The inductance should be 820μH,
the rated direct current should be 0.42A above.
Otherwise heating or abnormal oscillation occurs.
R1: For noise terminal
voltage reduction
10 to 22Ω 1/4W
Reduce the noise terminal voltage. Please set it, if necessary.
The constant value should be evaluated in set.
ZNR: Varistor
Varistor must be used. It protects this part from lightning surge and static
electricity.
