Technical Specifications:
- Manufacturer: Sanyo (or high-quality replacement component)
- Package Type: SIP-15 (Single In-line Package, 15-Pin, Specialized Compact Form Factor)
- Primary Applications: Replacement power stage for book-shelf stereo systems, mini-component systems, and multi-channel surround sound receivers.
- Condition: Brand New / New Old Stock (NOS).
Critical Installation Notice: Due to the high thermal density of the compact STK402 series, proper heat dissipation is mandatory. Completely scrape away old thermal pads or dried compound from the heatsink. Apply a uniform, thin layer of high-quality silicone thermal grease across the entire metal backing of the IC before screwing it down tightly.
