Developed using Sanyo's proprietary Insulated Metal Substrate Technology (IMST), this flagship thick-film hybrid integrated circuit functions as a high-output 1-channel (mono) Class-AB audio power amplifier, delivering a massive 120W continuous RMS and up to 180W maximum peak power into a 6Ω load.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features:\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHigh-Output Flagship Mono Design:\u003c\/strong\u003e Delivers a sustained 120W RMS (with under 0.4% distortion from 20Hz to 20kHz) and scales up to 180W max peak output, optimizing dedicated single-channel current delivery without dynamic clipping.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eClass-AB Fidelity:\u003c\/strong\u003e Combines heavy electrical driving headroom with linear, warm analog dynamics, making it perfect for dedicated bass modules and theater dialogue reproduction.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMiniaturized IMST Substrate:\u003c\/strong\u003e Employs an advanced, low thermal resistance aluminum substrate that uniformly spreads thermal load across the mounting base, compressing the physical package footprint by avoiding bulky discrete transistor layouts.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIntegrated System Protections:\u003c\/strong\u003e Features a built-in thermal protection grid and pin-configured paths optimized to seamlessly sync with external standby networks, speaker muting grids, and rapid 0.3-second load-shorting safety switches.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Sanyo (Original New Old Stock \/ High-Quality Replacement)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePackage Type:\u003c\/strong\u003e Compact SIP-13 \/ SIP-ZIP (13-Pin Layout with Metal Heatsink Plate)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRecommended Operating Voltage:\u003c\/strong\u003e ±51V (Maximum Supply Voltage: ±73V to ±78V Bipolar Symmetrical Rails)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOutput Load Impedance:\u003c\/strong\u003e Optimized for 6Ω speaker systems\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePrimary Applications:\u003c\/strong\u003e Main power block for high-wattage active home subwoofers, center channel blocks in surround sound theater receivers, and active stage monitors.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e Brand New \/ New Old Stock (NOS).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003eCritical Installation Notice: Because a 180W mono amplifier concentrates immense thermal energy into a tightly compressed surface area, perfect thermal bonding is non-negotiable. Completely clean off all old, crusty thermal residue from your aluminum chassis heatsink bracket. Prior to fastening the module down firmly, apply a fresh, thin, uniform coating of premium silicone thermal grease across the entire metal backing plate of the STK404-140S.\u003c\/em\u003e\u003c\/p\u003e","brand":"Sanyo","offers":[{"title":"New","offer_id":48038271680666,"sku":"SC0009","price":16.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/9477\/8778\/files\/34-STK404-140S_20Thick-Film_20Hybrid_20IC_20-_201-Channel_20Mono_20Audio_20Power_20Amplifier.jpg?v=1778962502","url":"https:\/\/prellelectronics.com\/products\/stk404-140s-sanyo-thick-film-hybrid-ic-180w-mono-amplifier","provider":"Prell Electronics","version":"1.0","type":"link"}
