Stk411-210e Datasheet

The STK411-210E is a thick-film hybrid Integrated Circuit (IC) manufactured by Sanyo (now part of Panasonic)

To block DC from the input signal. Feedback Resistors/Capacitors: To determine the gain.

If the original power rating is insufficient, or the STK411-210E fails repeatedly due to overheating, you can replace it with a without any circuit modification, as long as the physical footprint (SIP-18 package) is the same.

: Delivers up to 120W per channel into an 8-ohm load. Stk411-210e Datasheet

| Model | Power (6Ω) | Supply (±V) | Typical Application | |-------------|------------|-------------|--------------------------------| | STK411-210E | 45W | 28V | Mid-power stereo receiver | | STK412-210E | 60W | 32V | High-power mains amplifier | | STK410-210E | 30W | 24V | Compact system or portable PA | | STK413-210E | 70W | 35V | Professional audio mixer |

These values represent typical performance from the original datasheet.

The STK411-210E offers the best balance of power and thermal manageability for most home stereo applications. The STK411-210E is a thick-film hybrid Integrated Circuit

specifically built for high-fidelity audio applications, often found in home theater systems and shelf stereos. 1.

Lead-free and environmentally friendly versions exist. 3. STK411-210E Pinout and Schematic

The STK411-210E is now an obsolete component, and original Sanyo parts are becoming increasingly rare. As of 2025–2026, most large authorized distributors (such as Mouser, Digi-Key, or RS Components) do not carry it, as confirmed by its listing on Octopart.

The STK411-210E belongs to a series of "split power supply" amplifiers, meaning it requires both positive and negative DC rails to operate. Class AB (Hybrid Thick Film) Channels: 2 (Stereo) Package Type: ZIP-22 (Zig-zag In-line Package with 22 pins) Operating Temp: -40°C to +105°C
