Str F6267 Datasheet Pdf

For troubleshooting, a common practice is to disconnect the load (e.g., the horizontal output transistor) and connect a dummy load (like a 60W incandescent lamp) to the main B+ output. If the lamp lights up and the B+ voltage is present and stable, the STR-F6267 is likely functional, and the fault lies elsewhere in the secondary circuits.

Due to its versatility and efficiency, the STR-F6267 is frequently found in a variety of electronic devices: str f6267 datasheet pdf

Note: Some datasheets list a 5-pin configuration where the functions of pins 6-8 are not available. Always refer to the official Sanken datasheet for the exact pin count and functions of your specific device. For troubleshooting, a common practice is to disconnect
