The STK411-210E is a thick-film hybrid integrated circuit (IC) manufactured by Sanyo (now part of Panasonic), primarily used as a high-power audio amplifier. Key Technical Specifications
Commercial Use: Integrated into larger audio units for standard and commercial applications. Stk411-210e Datasheet
The STK411-210E represents a golden era of modular hi-fi amplification. While no longer in production, its datasheet reveals a robust, low-distortion, and easy-to-use amplifier IC that still serves vintage audio restoration well. Understanding its pinout, thermal requirements, and application circuit is essential for anyone looking to repair legacy equipment or build a retro-style stereo amplifier. The STK411-210E is a thick-film hybrid integrated circuit
use a high-quality aluminum heatsink with thermal paste. Running it without a heatsink will cause immediate failure. Short Circuit Protection: Output power : 210W (4Ω), 150W (6Ω), 100W
Package Type: Housed in a ZIP-22 (Zig-Zag In-line Package) with 22 pins.
