Stk411210e - Datasheet

The STK411210E is a Hybrid Audio Power Amplifier IC manufactured by Sanyo (now part of ON Semiconductor). "Hybrid" means it isn't just a single silicon chip; it is a thick-film module that integrates multiple transistors and resistors onto a ceramic substrate, all encased in a specialized plastic/metal package.

Because of this construction, the STK411210E offers excellent thermal dissipation and high reliability, making it a favorite for mid-range consumer audio equipment.

Manufacturer: Sanyo (On Semiconductor) Category: Audio Power Amplifiers Device Type: Class AB Audio Power Amplifier (Hybrid IC)

Values at Ta = 25°C (unless otherwise specified). Exceeding these ratings may damage the device.
