Description
The STK433-130 is a high-performance 2-channel (stereo) Class AB audio power amplifier hybrid IC manufactured by Sanyo. Capable of delivering a robust 150W per channel at 10% THD (or 100W at 0.4% THD), this module is the definitive replacement part for high-wattage home audio systems, premium bookshelf stereos, and professional-grade amplifiers.
Key Features:
- High Power Output: Delivers 150W + 150W of power, providing the high-current drive necessary for large speakers and subwoofers.
- Class AB Architecture: Combines audiophile-grade sound quality with the reliability and efficiency required for modern consumer electronics.
- Pin-to-Pin Compatibility: Part of Sanyo's standardized series, allowing for consistent thermal performance across the STK433 family.
- Built-in Protection: Includes standby and mute circuit support to ensure quiet power-up/down and protect downstream speaker components.
