Hannstar J Mv4 94v0 E89382 Boardview Top Jun 2026

This is HannStar's specific internal material and flammability classification. It indicates the type of dielectric material used to insulate the conductive copper layers.

The rating appears in the story of a failed inverter: if a high-side MOSFET shorted, the PCB didn't sustain flame—only charred tracks. That saved the panel. The E89382 traceability means you can request the exact prepreg stackup from UL, vital for high-speed differential pairs (LVDS clock at 135 MHz). hannstar j mv4 94v0 e89382 boardview top

Understanding the HannStar J MV-4 94V-0 E89382 Boardview: A Guide to Troubleshooting That saved the panel

The marking tells the fire safety story: the PCB substrate meets UL 94 V-0 rating, meaning it self-extinguishes within 10 seconds after flame exposure. This is standard for consumer electronics but essential here—this board probably sits near a backlight inverter or power supply. This is standard for consumer electronics but essential
