• High-power output capability in compact SIP package
• Wide operating voltage and temperature range

Applications

• Home theater systems
• Professional audio equipment
• Hi-Fi amplifiers

Procurement Notes

Verify component authenticity as this part is listed as no longer manufactured by the original producer. Sourcing may involve third-party distributors or surplus stock. Confirm lot dates and physical condition upon receipt. Ensure compatibility with existing thermal management solutions due to high power dissipation characteristics inherent to this hybrid module design.

Selection Notes

Select this component for applications requiring robust, high-power stereo amplification in a single package. Consider the 15-SIP form factor for board layout constraints. Verify that the system can support the required ±36V supply rails. Evaluate thermal requirements carefully, as the module dissipates significant heat during operation, necessitating adequate heatsinking.

Part Context

This component belongs to the STK433 series of hybrid audio power amplifiers. These modules integrate multiple discrete components into a single unit to simplify circuit design and reduce board space. The series is known for reliability in consumer and professional audio markets, offering a complete solution for multi-channel amplification needs.

Replacement Considerations

Check for equivalent hybrid modules from other manufacturers if new production units are unavailable. Verify pinout compatibility and electrical specifications such as power output and supply voltage ranges before substitution.
