Description
Premium 2-Channel AF Power Amplifier Module
The STK4161II is a high-performance thick-film hybrid integrated circuit designed by Sanyo. It is specifically engineered for high-fidelity stereo power amplification, providing a clean and powerful output of 35 Watts per channel.
Ideal for repairing vintage audio receivers or for use in high-end DIY amplifier projects, this module is known for its low harmonic distortion and robust thermal stability.
Key Technical Features:
- Output Power: 35W + 35W (at 8?, THD = 0.4%)
- Configuration: 2-Channel Stereo (Series II)
- Supply Voltage: Recommended ±30.5V (Max ±46V)
- Built-in Muting Circuit: Effectively eliminates "pop" noise during power-on/off.
- Thermal Efficiency: Features an improved substrate design for better heat dissipation.
Installation Requirements:
To ensure optimal performance and prevent thermal failure, this IC must be mounted to an appropriately sized heatsink. Always use a fresh layer of thermal silicone grease between the IC backplate and the heatsink surface.
Note: This is a 22-pin Single In-line Package (SIP). Please verify your pin configuration and voltage requirements before installation.
