Description
Bring clear, dynamic power back to your sound systems with the STK407-050. Precision-manufactured by Sanyo, this thick-film hybrid integrated circuit functions as a dual-channel (stereo) Class-B audio frequency power amplifier, delivering a stable 45W + 45W RMS output directly into 6Ω speaker configurations.
Key Features:
- Dual-Channel Power Output: Provides a steady 45W per channel configuration with excellent acoustic performance and minimal crosstalk.
- Built-In Thermal Sensor: Features an integrated internal thermal sensor for real-time case temperature tracking, safeguarding your circuit from over-temperature failures.
- Low Distortion Architecture: Engineered to hold total harmonic distortion (THD) down to a tight 0.05% (at 20Hz to 50kHz), preserving crisp highs and punchy lows.
- Power-Saving Standby Support: Fully compatible with external circuitry for low-power standby modes and automated power-switching.
- Suppressed Shock Noise: Internally optimized to drastically reduce power supply switching noise and speaker "pop" transients during boot cycles.
Technical Specifications:
- Manufacturer: Sanyo (or high-quality legacy component equivalent)
- Package Type: Case 3-15 / SIP-15 (Single In-line Package, 15-Pin Layout with Heatsink Backplate)
- Primary Applications: Main audio frequency power stage in home hi-fi stereo systems, bookshelf amplifiers, active subwoofers, and custom DIY sound builds.
- Operating Voltage Range: ±25V to ±41V (Bipolar/Symmetrical Power Supply)
- Condition: Brand New / New Old Stock (NOS).
Critical Installation Notice: Due to the high peak power capacity of this module, exceptional thermal bonding is non-negotiable. Thoroughly clean away old, dried thermal residue from your aluminum heatsink plate. Apply a fresh, thin, and uniform layer of silicone thermal grease across the entire metal backing plate of the STK407-050 prior to fastening it securely down.
