The alphanumeric string on your PCB is a combination of a manufacturer identifier and a flammability rating. It does not represent a single electronic component like an integrated circuit or a transistor. 1. The "94V-0" Meaning (UL 94 Standard)
The markings on a printed circuit board (PCB) do not refer to a single electronic component but rather to the board's manufacturer and its fire safety rating. Understanding the Markings
This is proprietary to the company that designed the device (e.g., LG, VIZIO, or Ford) and is rarely released to the public. The "94V-0" Safety Standard
The SH1 94V-0 is a widely used electronic component in various industries, including power supplies, lighting, and automotive applications. As a crucial part of many devices, it's essential to understand its characteristics, specifications, and applications. In this article, we'll provide an in-depth look at the SH1 94V-0 datasheet, covering its features, technical specifications, and uses. sh1 94v-0 datasheet
Given the ambiguity, enter a into your distributor search.
In many instances, "SH" corresponds to manufacturers like Shenghong Electronics , Shengyi Technology , or other major Asian laminate suppliers, with "1" indicating a specific factory production line or base material formulation (such as standard FR-4). Typical Specifications Found in an SH1 94V-0 Datasheet
Search the green or black solder mask of the PCB for a code starting with the letter (e.g., E123456). This is the UL File Number. Copy this "E number." Go to the official UL Product iQ database online. The alphanumeric string on your PCB is a
Read the text laser-etched onto the top black plastic casing of the damaged component (the IC chip, MOSFET, or diode).
For a set of 5 specimens, the total flaming combustion time cannot exceed 50 seconds.
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 The "94V-0" Meaning (UL 94 Standard) The markings
Maximum weight gain of 0.1% to 0.3% when exposed to water, protecting internal copper layers from corrosion and vapor expansion during soldering. How to Find the True Schematic for Your Board
The "94V-0" portion is a standardized plastic flammability rating defined by ( Standard for Tests for Flammability of Plastic Materials for Parts in Devices and Appliances ). This is a safety standard, not a performance specification.

The database will return the exact legal name and location of the factory that manufactured the board substrate (resolving exactly who "SH1" is), along with the thermal limits of the material (usually up to 130°C). Step 2: Search for the Application/Device Model
Instead, it identifies the specific fabrication house that manufactured the bare green, blue, or black fiberglass board.
