Stk413-430 Circuit Diagram 90%

To prevent high-frequency parasitic oscillations (which can overheat and destroy the IC), a Zobel network is connected from each output pin to the power ground. This consists of a (2W to 5W) resistor in series with a 100nF100 n cap F ) polyester film capacitor. Additionally, an inductor ( ) wrapped with a parallel

: Connected to a specific pin that, when triggered, silences the output to protect speakers from transient noise. stk413-430 circuit diagram

What your current power supply transformer outputs. The specific impedance rating ( ) of the speakers you intend to drive. What your current power supply transformer outputs

Pins 6 and 11 (NF – Ripple Filter) are often connected to ground via a 100µF capacitor to reduce power supply hum. A small resistor (220Ω) from these pins to ground may also be included. A small resistor (220Ω) from these pins to

Blown power supply fuses are a frequent secondary symptom of an IC failure. Replacement:

= 1 + (2200 / 56) ≈ 40.2 dB (times 40.2 V/V)
