STK404-140N-E
Overview
Thick-Film Hybrid IC
1ch class-AB Audio Power IC
180W
The STK404-140N-E is a hybrid IC for the audio power amplifier that mounts discrete components as the audio
power amplifier circuit in small space using the original Insulated Metal Substrate Technology IMST. The compact
package has been achieved by adopting the low thermal resistance substrate (our conventional model kind ratio).

[Note]
*1.
All tests are measured using a constant-voltage supply unless otherwise specified.
*2.
Thermal Detector temperature (+145°C±5°C) indicates the value at unusual operation, therefore, does not indicate
the guaranteed value at usual operation.
Thermal Detector is PRF18series (AS characteristic) manufactured by MURATA.
*3.
The output noise voltage is peak value of an average-reading meter with a rms value scale (VTVM).
A regulated AC supply (50Hz) should be used to eliminate the effects of AC primary line flicker noise.
*4.
Allowable time for load short-circuit and output noise voltage are measured using the specified transformer power
supply. About the load short circuit, it is designed assuming protecting by cut-off within 0.3 second.
*5.
