Premium Audiophile-Grade 30W Stereo Power Amplifier Module
The STK4151V is a high-performance thick-film hybrid integrated circuit from Sanyo's elite "V" series. This module is the preferred choice for audiophile-grade restorations, offering a significant jump in audio clarity over the standard STK4151II series.
With a continuous output of 30W + 30W, the STK4151V utilizes a specialized internal current mirror circuit to achieve an ultra-low Total Harmonic Distortion (THD) of just 0.08%. This results in a more transparent, detailed soundstage, making it ideal for high-fidelity home audio receivers and integrated amplifiers.
Key Technical Features:
- Continuous Power Output: 30W + 30W (at 8Ω, THD = 0.08%)
- Ultra-Low Distortion: 0.08% THD for professional-level audio fidelity.
- Configuration: 2-Channel Stereo (18-Pin SIP/HYB Package).
- Built-in Muting: Integrated circuit to suppress "pop" noise during power-on/off sequences.
- Operating Voltage: Recommended supply of ±27.5V (Absolute Maximum ±42V).
- Thermal Reliability: Guaranteed substrate temperature up to 125°C.
Installation & Safety:
To preserve the low-distortion characteristics of the "V" series, the STK4151V must be mounted to a clean, flat heatsink using high-quality thermal grease. It is pin-compatible with the STK4101II series, allowing for a high-fidelity upgrade in existing systems that use standard 18-pin STK modules.
Technician's Note: Verify that your power supply rails are symmetrical and within the ±27.5V range to ensure the best signal-to-noise ratio and module longevity.
