If the component is an IC (Integrated Circuit) and "SH1" is printed in tiny font, it might just be the lot code or date code.
Why this matters for your datasheet search: If you search for "SH1 94V0 datasheet," search engines get confused. They see a part number (SH1) and a safety code (94V0). You must isolate the part number.
Search engines treat "SH1 94V0" as a single entity. However, manufacturers separate this information:
Pro Tip: When you open a genuine SH1 datasheet, look for a small note in the "Package Specifications" section. It will say: "Molding compound: UL 94V-0 rated."
Depending on the suffix, the electrical characteristics change drastically. You might encounter:
