This is the most common scenario. A component manufacturer will list "UL94V-0" as a property of its plastic housing. For example, a datasheet for a Molex connector or a FR151 fast recovery rectifier will explicitly state that its plastic package meets the UL94V-0 flammability classification. You are not looking for a document called "94V-0", but a datasheet for a specific part that includes "94V-0" in its "Features" or "Materials" section.
Look past the UL stamps and search the silk-screened text on the edges of the board. You are looking for codes that look like this: EAX6XXXXXXX (Common on LG boards) BN44-XXXXX (Common on Samsung power supplies) sh1 94v-0 datasheet
: "SH" or "SH1" typically denotes the specific fabrication house or material series. 2. Physical & Mechanical Specifications Thickness Options : Standard ranges from Copper Weight : Typically per square foot. Surface Finish This is the most common scenario
