Stk411-210e Datasheet [repack] Info

The STK411-210E is a thick-film hybrid integrated circuit (IC) manufactured by Sanyo (now part of Panasonic). It is primarily designed as a high-efficiency 2-channel audio power amplifier with built-in power management features for high-fidelity audio systems and industrial applications. Key Technical Specifications

Thanks in advance.

Required External Components per Channel:

• Input coupling capacitor: 1–2.2 µF film or electrolytic (to block DC).
• Feedback shunt capacitor: 100 µF electrolytic + 0.1 µF film (for setting low-frequency cutoff).
• Feedback resistors: 680Ω (from output to inverting input) and 22kΩ (from inverting input to ground) → Gain ≈ 1 + (22k/680) ≈ 33.3× (30.5 dB).
• Zobel network: 10Ω/2W resistor + 0.1 µF capacitor (to ground) for high-frequency stability.
• Output inductor: 1–2 µH (optional, for capacitive load protection).
• Power supply decoupling: 4700 µF per rail for main smoothing, plus 100 nF ceramic near pins 3 and 6.

Designed for medium-power applications, often providing 10W+10W or higher depending on the specific supply voltage and load. Total Harmonic Distortion (THD): Stk411-210e Datasheet

Installation: Proper cooling is critical; users should ensure it is mounted to an adequate heatsink using thermal paste to prevent premature failure due to thermal stress. The STK411-210E is a thick-film hybrid integrated circuit
