Once you have identified the likely component type using the guide above, here is how to locate the document:
However, I can explain what those terms mean and help you find what you’re looking for:
A "94V-0" datasheet for any PCB material focus on fire safety metrics rather than just electrical performance:
Once you have downloaded a free PDF claiming to be the "SH1" datasheet, here is exactly where to verify the 94V-0 rating. sh1 94v0 datasheet free
Why is this specific combination (SH1 + 94V-0) so popular? Because it is the workhorse of low-voltage AC to DC conversion.

: The material will not drip flaming particles that could ignite surfaces below the device. Once you have identified the likely component type
Constant current driver for LED backlights in tablets like the Samsung Galaxy Tab and Lenovo Tab P11. Dimensions: Approximately 25mm x 18mm .
The "94V-0" portion is the most critical piece of information on the board. It refers to the standard, a plastics flammability test administered by Underwriters Laboratories (UL).
: Look for a code like E248779 or E239807 . | Parameter | Symbol | SH1 | SH2
If you are trying to fix a broken device and the only marking you see is "SH1 94V-0", do not give up. You can find the real technical documentation by looking for other clues on the board. Step 1: Look for the UL File Number (The "E" Number)
The designation refers to a specific type of printed circuit board (PCB) component, commonly used as a backlight driver or constant current plate in tablets and electronics. The "94V-0" part signifies that the board meets the highest UL 94 flammability standard , meaning it self-extinguishes within 10 seconds during fire testing. 1. Key Specifications of SH1 94V-0
To help point you in the right direction for your repair or design project, tell me:
Materials marked with SH1 94V-0, such as FR4 epoxy glass laminates , are chosen for their reliability in high-heat or high-risk electronic environments.
Understanding the SH1 94V-0 Circuit Board Specification An engineering or repair project often requires identifying specific components on a printed circuit board (PCB). Searching for an download usually means you are looking for technical specifications for a board stamped with these markings.
