Description
Restore crisp analog warmth and balanced power to your component audio systems with the STK402-050. Manufactured using Sanyo's unique Insulated Metal Substrate Technology (IMST), this genuine-spec thick-film hybrid integrated circuit acts as a dual-channel (stereo) Class-AB audio frequency power amplifier, providing a stable 30W RMS per channel continuous output (up to 45W peak) into 6Ω speaker loads.
Key Features:
- Dual-Channel Class-AB Efficiency: Combines low total harmonic distortion (down to 0.01% typ. at 1kHz) with robust power delivery for authentic sound staging.
- Miniaturized Low Thermal Resistance Substrate: Features a condensed baseplate layout that shrinks physical package volume by roughly 60% compared to vintage generations, allowing a seamless fit into tight PCB tracking layouts.
- Uniform Series Compatibility: Engineered within a pin-compatible framework spanning 20W to 120W per channel, meaning the underlying schematic trace can easily accept alternative grades during production design. It is also footprint-compatible with 3-channel (STK402-200 series) printed circuit board traces.
- Advanced Transient Mitigation: Pin-configured to link smoothly with external manufacturer standby microcontrollers, muting circuitry networks, and 0.3-second load-shorting protection arrays to fully suppress power-on "pop" transients.
Technical Specifications:
- Manufacturer: Sanyo (or high-quality premium legacy component equivalent)
- Package Type: Compact HYB-14 / SIP-14 Variant (14 Pin Active Layout with Metal Mounting Baseplate)
- Maximum Supply Voltage (No Signal): ±40V (Recommended Supply Voltage: ±26.5V)
- Output Load Impedance: Optimized for 6Ω speaker systems
- Primary Applications: Main audio output power stage in mini-stereo shelf sets, bookshelf amplifiers, mid-sized receivers, and active audio monitors.
- Condition: Brand New / New Old Stock (NOS).
Critical Installation Notice: Proper heat dissipation is vital to prevent catastrophic failure of the compact STK402 series. Thoroughly scrape away all old, hardened thermal compound from your amplifier's aluminum heatsink block. Apply a fresh, thin, and uniform layer of silicone thermal grease across the entire metal backing plate of the STK402-050 before tightening down the mounting screws.
