When you see stamped on a green, blue, or black circuit board, treat it as a certificate of flame safety and origin rather than a part number. To advance your troubleshooting, shift your focus away from this stamp and search instead for the UL "E" number to identify the factory, or the proprietary motherboard model number to find a working circuit diagram.
Near the "SH1 94V-0" text, you will almost always find a code that starts with an uppercase "" followed by 5 or 6 digits (e.g., E123456 ). Copy that "E" number.
Verified for IPC-TM-650 (thermal stress test) to withstand soldering processes.
Enter that E-number into the UL database to find the specific manufacturer and their material properties. sh1 94v-0 datasheet

Due to their reliable and standard-compliant nature, SH1 94V-0 boards are frequently found in: USB Port Boards (e.g., dual USB mounting boards). Power Supplies and AC Adaptors. Industrial Controllers and Consumer Appliance PCBs. Summary Table Designation Victory Giant Technology (Huizhou) Co., Ltd UL File Number Manufacturer Code SH / SH1 / SH10 / SH14 Flame Class V-0 (Self-extinguishing) Material Generally FR-4 Max Temperature Conclusion
If your product is sold in North America or Europe for high-voltage applications, power supplies, or automotive interiors, UL94V-0 is often a regulatory requirement. Using a non-V-0 connector could fail safety certification (e.g., CE, UL, TÜV). When you see stamped on a green, blue,
Here is what you are likely to encounter:
Using materials that do not meet 94V-0 standards can lead to catastrophic failure, including electrical fires. The, SH1 94V-0 classification is required in several sectors:
The "E248779" number often found printed next to "SH1 94V-0" is a UL File Number. A UL "Yellow Card" is the official datasheet for a certified material. It provides the exact thicknesses at which the material passed V-0, the "Relative Thermal Index" (RTI), and other crucial safety parameters. You can find these on the official UL Prospector database. Copy that "E" number
An electronics datasheet provides the technical specifications, operating limits, and performance characteristics of a specific component or material. When engineering or repairing electronic devices, understanding the designations on a printed circuit board (PCB) is critical.
Common component identifiers will look like LM317 (voltage regulator), 10N60 (MOSFET), or NE555 (timer). Searching for these numbers alongside the word "datasheet" will give you the exact pinouts and electrical tolerances you need for repairs.
