Because "SH1" is frequently a proprietary identifier for specific manufacturers (such as Rectron Semiconductor or various PCB fabricators in Shenzhen), you may need to look for documentation from the specific manufacturer. The Ultimate Guide To UL 94V-0 Circuit Boards - Jhdpcb
This article serves as a comprehensive resource. Whether you are trying to locate the official datasheet, understand the meaning of the 94V-0 rating, or find compatible parts for your next project, this guide covers everything you need to know. sh1 94v-0 datasheet
| Feature | Spec | |---------|------| | Pitch | 1.0 mm | | Circuits | 1 pin | | Current rating | 1 A | | Housing material | Nylon 66 or LCP, 94V-0 |
Look for a small backward "UR" logo followed by a letter "E" and a string of five to six digits (e.g., E123456). Inputting this number into the online UL Product iQ database will reveal the exact corporate identity of the factory that manufactured the raw PCB. | Rating | Orientation | Afterflame Time (Single)
The database will reveal the exact company name, legal address, and material datasheet for the factory that physically printed the board. 2. Locate the Primary Board Part Number
Look for numbers printed on three-pinned black components (e.g., IRF540N ). Whether you are trying to locate the official
Here is the direct truth: Consequently, a single, universal schematic datasheet for "SH1 94V-0" does not exist. Instead, this marking represents a critical manufacturing safety certification and a factory identifier.
If you are looking at a small electronic component (often a transistor, diode, or voltage regulator) with "SH1" written on it and "94V-0" printed on the PCB nearby, you are looking at two separate pieces of information.
The alphanumeric string on a circuit board is not a single part number, but rather a set of regulatory and manufacturing stamps:
The marking is typically a manufacturer's logo, factory code, or raw material identifier.
