: Parts from Littelfuse frequently feature this flammability rating.
In the world of electronics manufacturing, the "SH1 94V-0 datasheet" is a search query that often pops up for procurement officers, hardware engineers, and PCB designers. For the uninitiated, "SH1" and "94V-0" refer to two distinct but equally critical aspects of electronic components: a specific series of wire-to-board connectors (SH1) and a stringent flammability rating (94V-0).
| 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 |
). There is no single "datasheet" for this combination because 94V-0 is a universal industry standard rather than a specific electronic component. 1. Understanding the "94V-0" Rating The "94V-0" part of the marking is a flammability rating established by Underwriters Laboratories (UL) under the

When working with SH1 94V-0 materials, designers and engineers should consider the following implications:
