SH1 94V-0 only describes the raw, unpopulated fiberglass board (FR-4 material) before any copper traces are etched or components are soldered.
Used in engine control units (ECUs) and battery management systems that must withstand engine heat.
The material cannot drip molten, flaming plastic that could ignite a cotton pad placed below it. sh1 94v-0 datasheet
A controlled methane flame is applied to the bottom of the vertically mounted specimen for 10 seconds.
If you are troubleshooting a broken device with this board marking, use the following steps to find the actual technical documentation you need: Step 1: Look for the UL File Number SH1 94V-0 only describes the raw, unpopulated fiberglass
Because "SH1 94V-0" is a common board identifier, it appears in various hardware. Users frequently find this code on the internal power boards of:
Why would an engineer specifically filter by "94V-0"? Safety and reliability. These connectors are mandatory in: A controlled methane flame is applied to the
This is . It is a UL 94 Flammability Rating .
Look for a code starting with "E" followed by numbers (e.g., E248779 ). You can plug this into the UL Product iQ database to find the exact manufacturer.
The marking (often accompanied by ) typically refers to a specific Printed Circuit Board (PCB)
