POWER BLOCK APPLICATION NOTES

Output Noise

The figure below ia a sample diagram to reduce Output Ripple

and Noise.

EMI

The figure below ia a suggested diagram to reduce

Electromagnetic Interference (EMI).

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.

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
