Description and Introduction

3ch AF Power Amplifier(Split Power Supply) 10W+10W+10W,THD=0.4% The STK400-490 is a hybrid IC (Integrated Circuit) power amplifier module manufactured by Sanyo (SK). Here are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Type:** Hybrid IC (Thick Film)  
- **Function:** Power Amplifier  
- **Output Power:** 50W (per channel, min. at 8Ω, THD = 0.4%)  
- **Supply Voltage Range:** ±35V to ±42V (recommended)  
- **Total Harmonic Distortion (THD):** 0.4% (typical)  
- **Frequency Response:** 20Hz - 20kHz  
- **Gain:** 40dB (typical)  
- **Input Resistance:** 55kΩ  
- **Load Impedance:** 4Ω to 8Ω  
- **Operating Temperature Range:** -20°C to +75°C  

### **Descriptions:**  
- The STK400-490 is a stereo power amplifier module designed for high-fidelity audio applications.  
- It integrates multiple amplifier stages into a single hybrid IC, reducing external component requirements.  
- The module is commonly used in home audio systems, amplifiers, and stereo receivers.  

### **Features:**  
- **High Power Output:** Capable of delivering 50W per channel into an 8Ω load.  
- **Low Distortion:** THD of 0.4% ensures clear audio reproduction.  
- **Built-in Protection:** Includes thermal shutdown and overcurrent protection.  
- **Compact Design:** Hybrid construction allows for space-efficient PCB mounting.  
- **Wide Voltage Range:** Supports dual power supply operation (±35V to ±42V).  

This information is based solely on the manufacturer's specifications and datasheet.
