PDF document named after the 2SC5332 part number, filed here under schematics but most likely a component datasheet rather than a board diagram. Under the Japanese JIS scheme, a 2SC prefix marks an NPN bipolar transistor, so expect absolute maximum ratings, electrical characteristics, package outline and pinout. The name gives no maker or device, so confirm the marking on the actual part first. At 178 KB it opens in any PDF reader and helps a technician choose a substitute or check base, collector and emitter orientation.
