The designation typically refers to a printed circuit board (PCB) identifier where "SH1" is a manufacturer's model or batch code, and "94V-0" is a critical safety rating defined by Underwriters Laboratories (UL). These boards are commonly found in high-reliability consumer electronics, such as smartphone internals (e.g., OnePlus or Samsung) and power adapters. Understanding the 94V-0 Rating
The most important fact to understand is this:
The designation refers to a specific type of Printed Circuit Board (PCB) material manufactured by Shengyi Technology Co., Ltd. (SYTECH) sh1 94v0 datasheet free
The "SH1" designation typically refers to a series of or Rectifier Diodes , most commonly associated with manufacturers like Shindengen , Sanken , or Semikron , though generic equivalents exist across the Asian semiconductor market.
Searching for an "SH1 94V-0" datasheet can be confusing because "94V-0" is not a specific model number for a component, but rather a safety rating for the material it is made of. What "SH1 94V-0" Actually Means The designation typically refers to a printed circuit
Many technicians and engineers search for the download online, hoping to find a schematic or electrical pinout for their specific board. However, there is a fundamental misunderstanding about what this alphanumeric code actually means.
To help me find a more specific datasheet, could you provide the (usually starts with 'E' followed by several digits) or the brand name printed near the "SH1" mark? The Ultimate Guide To UL 94V-0 Circuit Boards - Jhdpcb (SYTECH) The "SH1" designation typically refers to a
The burning board cannot drip flaming particles that could ignite a piece of surgical cotton placed underneath it.
If your board features a backward "UR" logo followed by a code starting with "E" (e.g., E213441 ), this is a UL tracking number. You can enter this code into the free online . This will reveal the exact name of the company that manufactured the raw circuit board, which can point you toward the correct corporate support channels. Summary of PCB Markings Marking Found Can you find a datasheet? 94V-0 Flammability safety rating No (Standard specification only) SH1 / SH-1 Factory raw laminate code No (Internal factory identifier) EXXXXXX (e.g., E173873) UL Manufacturer File Number Yes (Reveals the company name via UL Lookup) Model No. (e.g., Compal LA-9999P) Actual device design schematic Yes (Often available on repair forums)
