Datasheet-style document for the 2SC4617, marked revision 0 in the file name and stored as a 128 KB PDF under the schematic category. In JIS numbering the 2SC prefix denotes an NPN high-frequency transistor. Technicians use such a sheet to read terminal assignment, absolute maximum ratings, hFE ranges and outline drawings when testing a part out of circuit or choosing a substitute. Note that a revision 0 sheet may predate later corrections, so newer manufacturer revisions are worth comparing.
