(200W min,THD = 0.4%)
Features
Package Dimensions
• Compact package for thin-type audio sets
unit: mm
• Member of pin-compatible series with outputs of 20 to
200W
4051A
• Easy heatsink design to disperse heat generated in thin-
type stereo sets
[STK4050II]
• Constant-current circuit to reduce supply switch-on and
switch-off shock noise
• External supply switch-on and switch-off shock noise
muting, load short-circuit protection, thermal shutdown
and other circuits can be tailored-designed.

Notes.
All tests are measured using a constant-voltage supply unless otherwise specified.
Output noise voltage is measured using the transformer supply specified below.
The output noise voltage is the peak value of an average-reading meter with an rms value scale.The noise voltage waveform does not inl-
cude any pulse noise.
