MECHANICAL SpECIFICATIONS
pOwER bLOCk AppLICATION NOTES
Output Noise
The figure below ia a sample diagram to reduce Output Ripple
and Noise.
C1 = Electrolytic Capacitor
Capacitance = 22uF - 220uF
Voltage = Two times rated output voltage
L1 = 3uH - 10uH
C2 = Electrolytic Capacitor
Capacitance = 22uF - 47uF
Voltage = Two times rated output voltage
C3 = Ceramic Capacitor
Capacitance = 0.01uF - 0.1uF
Voltage = 50 volt
Notes:
1. The use of C1 alone may reduce noise to desired levels,
if not use L1, C2 and C3 in addition to C1.
2. The figure above is a suggested circuit. Only by trying true
application can levels be tested.
EMI
The figure below ia a suggested diagram to reduce
Electromagnetic Interference (EMI).
C1 = 0.22uF X Capacitor
L1 = 10mH - 30mH Common Mode, Choke
C2, C3 = 220pF Y Capacitors
Notes:
The diagram above is a recommended circuit, only by trying
true application can levels be measured.
Inrush Current
If desired, the use of a Choke, NTC or Inrush Current Limiter
may be used to reduce the Inrush Current
