Description
High-Fidelity 100W Mono Power Amplifier Module
The STK4044V is a high-power thick-film hybrid integrated circuit from Sanyo's prestigious "V" series. Delivering a continuous 100 Watts of output, this module is specifically engineered for high-fidelity audio applications where clean, uncolored power is a necessity. The "V" series revision features an internal current mirror circuit that reduces Total Harmonic Distortion (THD) to a mere 0.08%.
This mono module is a staple in the restoration of high-end vintage stereo receivers (used in pairs), high-output center channel speakers, and professional-grade guitar or keyboard amplifiers.
Key Technical Features:
- Continuous Power Output: 100W min (at 8Ω, 20Hz to 20kHz, THD = 0.08%)
- Distortion Performance: Low 0.08% THD for professional-level sonic clarity.
- Frequency Response: Full-range reproduction from 20Hz to 50kHz.
- Voltage Range: Recommended supply of ±51V (Absolute Maximum ±73V).
- Integrated Protection Support: Supports additional circuits for thermal shutdown, load-short protection, and power-on/off muting.
Installation & Thermal Management:
Due to its massive 100W output, the STK4044V generates substantial heat. It must be securely mounted to a large, flat heatsink using high-quality thermal silicone grease. Operating the module without a heatsink—even for testing—will result in immediate internal substrate failure.
Technician's Note: Before installation, check your power supply rails for symmetry and ripple. For the best "V-series" performance, ensure your supply remains near the recommended ±51V under load.
