Sh1 94v-0 Datasheet !!link!! < QUICK – SOLUTION >
The "E248779" number often found printed next to "SH1 94V-0" is a UL File Number. A UL "Yellow Card" is the official datasheet for a certified material. It provides the exact thicknesses at which the material passed V-0, the "Relative Thermal Index" (RTI), and other crucial safety parameters. You can find these on the official UL Prospector database.
Resistance to warping during reflow soldering. Why 94V-0 is Essential in Electronics Design
Before diving into the technicalities of flammability, it is essential to understand that "SH1 94V-0" is not a single type of component, but usually a marking with two distinct parts.
: The highest standard rating for self-extinguishing materials in this category.
SH1 94V-0 only describes the raw, unpopulated fiberglass board (FR-4 material) before any copper traces are etched or components are soldered. sh1 94v-0 datasheet
near the "SH1" mark, I can help you find the exact schematic or service manual. SH8 THRU SH1 - Mouser Electronics
: This rating is a baseline requirement for consumer electronics, automotive, and industrial equipment to prevent the spread of fire. Comparative Flame Ratings at a Glance Test Orientation Burn Time (Seconds) Flaming Drips Allowed? 94V-0 ≤is less than or equal to No 94V-1 ≤is less than or equal to No 94V-2 ≤is less than or equal to Yes HB Horizontal Slow burn (< 76mm/min)
If you are repairing electronics, sourcing parts, or designing printed circuit boards (PCBs), you have likely seen the marking stamped directly onto a circuit board.
If you are trying to troubleshoot a broken consumer device, household appliance, or power supply marked "SH1 94V-0", looking up that text will not give you a circuit schematic. To find the exact functional schematic or component layout, look for these alternative markings on the board: The "E248779" number often found printed next to
(A1, A1 mini). If you are looking for a datasheet to repair or integrate this board, here is the technical breakdown: 1. Board Specifications
Search for strings like REV: 1.0 or a long string of letters and numbers near the edge of the 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.
Measures how easily the material stores electrical energy. Standard 94V-0 FR-4 typically ranges from 4.2 to 4.8 at 1 GHz, which is crucial for high-speed signal routing. You can find these on the official UL Prospector database
The maximum continuous temperature the board can withstand safely, usually rated between 105°C and 130°C .
Go to the online, enter that E-number, and it will reveal the exact company that manufactured the raw PCB, along with their official material datasheet limits. Step 2: Locate the Appliance Model Number
Across 5 samples, the total burn time cannot exceed 50 seconds .
"SH1" is a proprietary factory identification code or logo assigned to a specific PCB fabricator.
