The 2SC4485 data sheet arrives as a 133 KB PDF, categorised as a schematic but documenting a single NPN bipolar transistor per the JIS 2SC prefix. No manufacturer or package information appears in the name. Read it for voltage and current limits, gain ranges and the pin diagram. During repair it guides lead identification and substitute selection. Verify the original part number on the body and match the package outline to the PCB footprint before fitting.
