The STK413-430 is part of a series that shares similar pinouts but differs in power output and voltage requirements.
: It is recommended to include a Zobel network (a resistor and capacitor in series) at the output to ensure stability under different speaker loads. 3. Safe Installation Guide stk413-430 circuit diagram
The STK413–430 series are hybrid audio power amplifier modules (commonly produced as STK413/416/418/420/425/430, etc.) used in consumer stereo and AV equipment. Each STK module integrates discrete power transistors, biasing, and protection components into a single package, providing a compact way to build high-power amplifier channels with fewer external parts. Typical use is in bridged or single-ended class-AB audio outputs for home receivers. The STK413-430 is part of a series that
