94v-0 Schematics — Mv-4

If you saw “MV-4 94V-0” on a board, it usually means:

The MV-4 94V-0 is a classification of printed circuit boards (PCBs) that meet specific safety standards for electrical devices. The "MV-4" refers to the board's material, construction, and performance characteristics, while "94V-0" is a flammability rating assigned by Underwriters Laboratories (UL). In this paper, we will explore the requirements and implications of designing and manufacturing PCBs that meet the MV-4 94V-0 standard. mv-4 94v-0 schematics

The MV-4 classification refers to a specific set of requirements for PCBs, including: If you saw “MV-4 94V-0” on a board,

- PCB: FR-4, UL 94V-0 - 4 layers (MV-4 stack-up) - Copper weight: 1 oz outer / 0.5 oz inner - Solder mask: both sides - Silkscreen: white, lead-free compatible The MV-4 classification refers to a specific set

+5V_IN → Fuse (rated for 94V-0 board) → Ferrite → 3V3 regulator
