Description
Restore ultimate high-power performance and clean, chest-thumping analog audio dynamics to your premium sound systems with the STK401-130. Precision-manufactured by Sanyo, this heavy-duty thick-film hybrid integrated circuit operates as a dual-channel (stereo) Class-AB audio frequency power amplifier, delivering a commanding minimum of 100W RMS per channel into low-impedance speaker setups.
Key Features:
- High-Power 100W Stereo Stage: Rated at 100W + 100W minimum continuous RMS (with dynamic headroom up to 130W per channel), offering incredible acoustic punch for demanding floor-standing stereo towers.
- Low-Impedance Load Stability: Explicitly engineered to remain electrically stable and cool under demanding 6Ω and 3Ω speaker configurations, matching high-end consumer speaker architectures perfectly.
- Optimized Block Pin Arrangement: Pin assignments are intelligently partitioned into physical input, output, and power supply grid blocks. This design simplifies PCB trace repair layouts and significantly minimizes pattern crosstalk and background noise.
- Streamlined Circuit Profile: Features a modernized internal design that eliminates the need for external bootstrap resistors and bootstrap capacitors, creating a more reliable, fewer-component repair.
Technical Specifications:
- Manufacturer: Sanyo (Original New Old Stock / High-Quality Replacement)
- Package Type: Multi-Pin SIP-ZIP / HYB-16 (16-Pin Array with Heavy Aluminum Baseplate)
- Maximum Supply Voltage (Vcc max): ±70V (Typical Operating Voltage: ±47V)
- Total Harmonic Distortion (THD): Ultra-linear 0.02% typ. (at 1kHz, 30W output)
- Primary Applications: High-end home theater AV surround receivers, premium karaoke systems, component stereo mainframes, and active professional subwoofers.
- Condition: Brand New / New Old Stock (NOS).
Critical Installation Notice: Due to the high 100W+ power capacity of this module, it generates substantial concentrated heat under load. Completely clean away all old, hardened thermal paste from your chassis heatsink plate. You must apply a fresh, thin, and uniform layer of high-quality silicone thermal grease across the entire metal backing plate of the STK401-130 prior to bolting it down tightly.
