Description
High-Fidelity 30W Mono Power Amplifier Module
The STK4028X is a premium thick-film hybrid integrated circuit from Sanyo's legendary "X" series. Designed for audiophile-grade performance, this module delivers a robust 30 Watts of power with an ultra-low Total Harmonic Distortion (THD) of just 0.018%, ensuring crystal-clear sound reproduction and high signal purity.
As a mono (single-channel) module, the STK4028X is a critical component for high-end center channel speakers, active monitors, and mono-block configurations where professional-level sonic transparency is the top priority.
Key Technical Features:
- Continuous Power Output: 30W min (at 8Ω, THD = 0.018%)
- Ultra-Low Distortion: 0.018% THD provides studio-quality audio reproduction.
- Internal Architecture: Utilizes a specialized current mirror circuit for superior linearity.
- Frequency Response: Optimized for high-bandwidth audio from 20Hz to 50kHz.
- Operating Voltage: Recommended supply of ±27.5V (Absolute Maximum ±42V).
- Slim Design: Compact packaging allows for slimmer audio set designs without sacrificing thermal stability.
Installation & Thermal Management:
Due to its high-precision architecture, the STK4028X is sensitive to heat. It must be securely mounted to a flat heatsink using high-quality thermal grease. Proper installation is critical to maintain its low-distortion characteristics and to prevent internal thermal failure.
Technician's Note: Verify that your power supply rails are symmetrical and within the recommended ±27.5V range to fully realize the "X" series' high-fidelity performance. Always check output emitter resistors for damage before powering up a new module.
