Short 125 KB PDF on the 2SC5086FT, the FT-suffixed variant of the 2SC5086 NPN transistor; the name does not say what the suffix means, though such suffixes usually mark…

PDF document for the 2SC4853, a part number following the Japanese JIS scheme in which the 2SC prefix marks an NPN bipolar transistor.

Labelled 1SS268, this 126 KB PDF appears to be a datasheet for a single component even though the index lists it as a schematic.

Named simply 80SQ, this 125 KB PDF is indexed as a schematic, but the code looks like a series designation for a rectifier diode family rather than a circuit diagram…

An uninformative name, 80CNQ, labels this 124 KB PDF filed among schematics. Without a suffix the file probably covers a whole component family rather than one rating…

A small PDF of 48.8 KB indexed under schematics, whose name points to a 44-lead PLCC package, most likely a package outline or socket drawing rather than a full circuit…
