Ordering number : EN*A1686
Thick-Film Hybrid IC
STK404-100SC-E 1-channel class AB audio
power IC, 90W
Overview
The STK404-100SC-E series is 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).
Applications
Audio power amplifiers.
Features
Pin-to-pin compatible outputs ranging from 90W to 180W
Miniature package (46.6mm×25.5mm×8.5mm, 59.2mm×25.5mm×8.5mm)
Output load impedance RL=6Ω supported.
Allowable load shorted time: 0.3s
Allows the use of predesigned applications for standby, mute, and the load short protection circuit.

[Remarks]
*1. Unless otherwise specified, use a constant-voltage power supply to supply power when inspections are carried out.
*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 PRF21series (AS characteristic) manufactured by MURATA.
*3. The output noise voltage values shown are peak values read with a VTVM. However, an AC stabilized (50Hz)
power supply should be used to minimize the influence of AC primary side flicker noise on the reading.
*4. Use the designated transformer power supply circuit shown in the figure below for the measurement of allowable
load shorted time and output noise voltage.
*5. Thermal design must be implemented based on the conditions under which the customer’s end products are
expected to operate on the market.
