Sh1 — 94v-0 Datasheet

SH1 94V-0 is not a specific electronic component but rather a safety marking found on Printed Circuit Boards (PCBs). This marking indicates that the board's substrate material meets the UL 94V-0 flammability standard, the highest rating for fire resistance in plastics used for electronics. Understanding the Marking

When you see "SH1 94V-0" on a circuit board, it communicates two distinct pieces of information:

94V-0: A standard established by Underwriters Laboratories (UL) that tests how quickly a material self-extinguishes.

SH1: Typically a manufacturer-specific identifier or a factory code used by PCB fabrication houses like Shenghua or similar manufacturers to trace the board's origin and UL file. Key Specifications of UL 94V-0

Materials with this rating must pass a vertical burn test, where a flame is applied to a sample in a vertical position. The criteria include:

Self-extinguishing: The material must stop burning within 10 seconds after the flame is removed. sh1 94v-0 datasheet

No Flaming Drips: The board cannot drip flaming particles that could ignite surrounding components.

Total Burn Time: The total duration for five samples must not exceed 50 seconds. Why This Rating Matters

Standardizing on 94V-0 is critical for high-risk or mission-critical applications:

Safety: It prevents the PCB from becoming a source of fuel during a fire, which is essential in consumer electronics, automotive, and industrial tools.

Thermal Stability: These boards often offer good thermal stability, typically maintaining integrity up to 130–150°C. SH1 94V-0 is not a specific electronic component

Compliance: Many international markets require UL 94V-0 certification for electronic products to ensure they meet safety regulations.

For further verification of a specific board, you can often search the UL file number (usually printed near the 94V-0 mark) on the UL Product iQ database. Sh1 94v-0 Datasheet Apr 2026

I cannot prepare a full, original technical datasheet for a part number like "SH1 94V-0," as this appears to be a combination of a partial or unclear manufacturer part code ("SH1") and a safety standard ("94V-0").

Here is why, along with what you likely need and how to find the correct document.

1. "SH1" – The Component Marking Code

SH1 is typically a top marking code for a surface-mount device (SMD). It is not the full part number. Component Type : The SH1 94V-0 is likely

Part 2: The SH1 Connector Series – Technical Specifications

The JST SH1 series is an industry standard for compact, high-density connections. It is widely used in consumer electronics, medical devices, and portable gadgets due to its small pitch and reliable contact.

Overview

• Component Type: The SH1 94V-0 is likely a type of fuse or a protective device used in electronic circuits.
• UL Rating (94V-0): This rating signifies that the material used for the component has achieved a UL 94V-0 classification. The UL 94 standard is used to assess the flammability of materials used in electrical devices. A 94V-0 rating means the material has demonstrated the highest level of flame retardancy; it does not burn for more than 10 seconds after being exposed to a flame, and it does not drip flaming particles.

4. How to Find the Correct Datasheet

1. Check the full marking – SH1 may be partial. Example: "SH1 43" = SH1 Schottky, date code.
2. Look at the component –
   • Two leads + black epoxy → diode
   • Small plastic box + metal contacts → connector
3. Search with manufacturer name – e.g., "Diodes Inc SH1 datasheet" or "JST SH1 94V-0"
4. Use parametric search on Mouser, DigiKey, or Octopart with "94V-0" plus package type.

Step 1: Go to the Source

Always start with the manufacturer:

• JST Official Website: Visit www.jst.com and navigate to "Products" > "Wire to Board Connectors" > "SH Series."
• Distributor Websites: Digi-Key, Mouser, or Arrow Electronics host official PDF datasheets. Search for "SH1-94V-0."

What is UL 94?

UL 94 is a standard for the flammability of plastic materials used in devices and appliances. It is published by Underwriters Laboratories (UL). The test involves holding a flame to a vertically oriented sample.

Step 2: Look for the Critical Markings

On the physical connector or within the datasheet drawing, verify the following:

1. UL File Number: e.g., E60389.
2. Flammability Statement: The datasheet must explicitly state "Housing: UL94V-0" in the materials table.
3. Temperature Rating: V-0 materials often have a higher heat deflection temperature (HDT). Ensure the datasheet lists the operating temperature compatible with your reflow soldering process.
