Description
Restore clean, continuous high-power low frequency performance or crisp vocal clarity to your sound system with the STK404-130S. Fabricated using Sanyo's proprietary Insulated Metal Substrate Technology (IMST), this genuine-spec thick-film hybrid integrated circuit acts as a high-output 1-channel (mono) Class-AB audio power amplifier, delivering 100W continuous RMS and up to a massive 150W peak dynamic output into a 6Ω load.
Key Features:
- High-Wattage Mono Configuration: Delivers a sustained 100W RMS (with under 0.4% distortion from 20Hz to 20kHz) and scales effortlessly to a 150W peak, optimizing current delivery for single high-demand channels without dynamic clipping.
- Class-AB Musical Precision: Blends robust power headroom with ultra-low crossover distortion, ensuring punchy, warm, and highly linear analog sound reproduction.
- Advanced IMST Thermal Substrate: Built on a modern low thermal resistance aluminum substrate that shrinks physical package volume and evenly spreads thermal loads compared to bulky discrete layout templates.
- Integrated System Protections: Features a built-in internal thermal protection network and is pin-configured to tie cleanly into external microcontrollers for automated standby, speaker muting grids, and rapid 0.3-second load-shorting safeties.
Technical Specifications:
- Manufacturer: Sanyo (Original New Old Stock / High-Quality Replacement)
- Package Type: Compact HYB-13 / SIP-13 (13-Pin Layout with Metal Mounting Base)
- Recommended Operating Voltage: ±45V (Maximum Supply Voltage: ±64V to ±70V Bipolar Symmetrical Rails)
- Output Load Impedance: Optimized for 6Ω speaker systems (supports 4Ω to 8Ω configurations)
- Primary Applications: Main power block for high-output active home theater subwoofers, center-channel modules in multi-channel AV surround setups, and active instrument amplifiers.
- Condition: Brand New / New Old Stock (NOS).
Critical Installation Notice: High-power mono amplifier modules concentrate substantial thermal energy into a condensed surface area. Completely clean off all old, hardened thermal compound from your aluminum chassis heatsink bracket. Prior to fastening the module down firmly, apply a fresh, thin, and uniform coating of premium silicone thermal grease across the entire metal backing plate of the STK404-130S.
