REV: 1.0 or REV: A adjacent to a longer alphanumeric string.
Scan the board for a code that starts with the letter (e.g., E123456 ). This is the UL File Number. Copy that exact number.
: Houses the potentiometer (control knob) and LED indicators for the printer's user interface. Connector Type
"SH1" is typically a proprietary logo, brand identifier, or factory tracking code belonging to a specific PCB manufacturer. sh1 94v-0 datasheet
| If you see... | It means... | What to download | |---------------|-------------|------------------| | SH1 on SOT-23 | BSS138 MOSFET (most likely) | BSS138 datasheet | | SH1 on SOT-89 | Possibly MMBT3904 (check) | MMBT3904 datasheet | | 94V-0 on PCB | UL94 flammability class V-0 | UL 94 standard (not a component datasheet) | | "SH1 94V-0" on same line | Component marking + PCB rating | Two separate documents |
When a board features the 94V-0 stamp, it has passed rigorous vertical burn tests:
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. REV: 1
The "94V-0" in the marking is the most critical piece of information. It is a defined by Underwriters Laboratories (UL), a global safety science company. Ignoring this rating in product design can lead to safety failures and non-compliance with international regulations.
Materials with an SH1 94V-0 rating are commonly used in various electrical and electronic applications where flame retardancy is critical, such as:
This article provides a comprehensive overview of what the marking means, the specifications behind the UL 94V-0 rating, and why this datasheet information is critical for design engineers and safety compliance. What is the SH1 94V-0 Designation? Copy that exact number
Look for numbers printed on three-pinned black components (e.g., IRF540N ).
When you search for an "SH1 94V-0 datasheet," you are essentially looking for the technical documentation of a product that uses the or has that safety certification . It is highly unlikely you will find a datasheet titled "SH1 94V-0.pdf". Instead, the "94V-0" rating will be a key feature listed in the datasheet of a specific component, PCB assembly, or raw material.
: Options like HASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold), or OSP (Organic Solderability Preservatives). Peel Strength
, which is the highest safety standard for vertical burn resistance in plastics. It indicates the board will self-extinguish within 10 seconds of being exposed to a flame.
