etched onto a green or blue board, here is what it actually tells you:
The designation typically refers to a specific marking found on printed circuit boards (PCBs) or electrical components, often associated with manufacturers like SHI (Shin Hwa) or components for brands like Vizio and LG . It indicates that the board's substrate material meets the UL 94V-0 flammability standard , the highest level of flame retardancy for plastics . Key Specifications & Features
High insulation resistance prevents arcing and short circuits, even under high-voltage conditions. Low Dielectric Constant ( Dkcap D sub k ): Suitable for high-frequency signal integrity. 3. Mechanical Strength
Medical devices or automotive electronics where a fire could be catastrophic. 💡 How to find the Actual Datasheet
(typically >130°C to 170°C), ensuring stability at higher operating temperatures. 2. Electrical Properties sh1 94v-0 datasheet
Here is a comprehensive guide to understanding the marking, what it means for your hardware, and how to interpret the technical data associated with it. What Does "SH1 94V-0" Mean?
| Issue | Recommendation | |-------|----------------| | "SH1" not listed in major datasheet databases | Likely a house marking or obsolete part. Try SH1-xxxxF or similar. | | 94V-0 listed but no electrical data | That's correct – 94V-0 is material , not function. Find main datasheet elsewhere. | | Counterfeit or incomplete datasheets online | Always check manufacturer (Vishay, ON Semi, JST, Molex). Avoid random PDF hosting sites. |
Practical examples of where "SH1 94V-0" appears include:
When a PCB material achieves a , it has passed rigorous vertical burn tests: etched onto a green or blue board, here
Because these markings are often etched or silk-screened together, they represent the board's origin and its safety credentials. :
Searching these specific model numbers online will help you find service manuals or replacement boards. Step 2: Look up the UL File Number (The "E" Number)
When you see "SH1 94V-0" on a circuit board, it communicates two distinct pieces of information:
In many historical UL directories, marks starting with "SH" correspond to large-scale Asian PCB fabricators (such as Shenzhen Shenditong Electronic, Shingtech, or similar board houses). It means that specific company pressed, etched, and laminated the bare green fiberglass board. What Does "94V-0" Mean? Low Dielectric Constant ( Dkcap D sub k
This guide explains what the SH1 94V-0 marking means, how to decode it, how to find the actual manufacturer using UL databases, and what to do when you need a circuit diagram for troubleshooting. Deconstructing the Code: What Does "SH1 94V-0" Mean?
Therefore, searching for "SH1 94V-0 datasheet" will never yield a circuit diagram. The stamp only tells you what the blank board is made of, not how the copper traces are laid out or what components are soldered onto it. How to Find the Real Datasheet or Schematic
This is the datasheet for the bare circuit board material itself. The global standard for 94V-0 PCBs is FR-4 (Flame Retardant 4) . An FR-4 datasheet will include mechanical, thermal, and electrical properties, and will explicitly state it is UL rated (94V-0) . Key properties in an FR-4 datasheet you should look for are:
The flame is removed, and technicians time how long the material glows or burns.
Therefore, when searching for an "SH1 94V-0 datasheet", you are generally looking for the technical specifications of the component or PCB that bears that chassis code, with "94V-0" being the critical safety specification.
