Housed in a ZIP-22 (Zig-Zag In-line Package) or DIP-22P module, which facilitates easy mounting on a heatsink.
Built-in thermal shutdown protection prevents damage by disabling the amplifier if internal temperatures exceed safe limits (often around 125°C substrate temperature).
Approximately 105 watts per channel (into an 8-ohm load). Stk411-210e Datasheet
The is a high-performance 2-channel audio power amplifier hybrid integrated circuit (IC) manufactured by Sanyo . Designed primarily for home theater systems, professional sound equipment, and high-fidelity stereo applications, it is part of the renowned STK series known for robust output and consistent audio quality. Key Technical Specifications
According to technical summaries from Alibaba and other electronic component databases, the STK411-210E features: Housed in a ZIP-22 (Zig-Zag In-line Package) or
The STK411-210E was a staple in 1990s and early 2000s audio equipment but has since been by Sanyo/Panasonic.
It supports Bridge-Tied Load (BTL) configurations, allowing the two channels to be combined for high-power mono output (potentially up to 400W depending on the setup). Application and Sourcing Guide The is a high-performance 2-channel audio power amplifier
The STK411-210E is a , meaning it integrates discrete transistors and resistors on a ceramic substrate to optimize heat dissipation.
Typically remains below 0.1% to preserve audio signal integrity. Pinout and Internal Architecture
Specified for operation from -40°C to 105°C (TA).
