POWER BLOCK APPLICATION NOTES
Output Noise
EMI
C1 = Electrolytic Capacitor
Capacitance = 22uF - 220uF
Voltage = Two times rated output voltage
C1 = 0.22uF X Capacitor
L1 = 3uH - 10uH
C2, C3 = 220pF Y Capacitors
C2 = Electrolytic Capacitor
Capacitance = 22uF - 47uF
Voltage = Two times rated output voltage
Notes:
The figure below ia a sample diagram to reduce Output Ripple
and Noise.
C3 = Ceramic Capacitor
Capacitance = 0.01uF - 0.1uF
Voltage = 50 volt
Notes:
The figure below ia a suggested diagram to reduce
Electromagnetic Interference (EMI).
L1 = 10mH - 30mH Common Mode, Choke
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
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.
