Transistor reference for the 2SC3325 in a 196 KB PDF, catalogued as a schematic but most probably a datasheet. Under JIS numbering the 2SC prefix marks an NPN bipolar device. Typical contents are maximum ratings, gain and frequency characteristics, graphs and the outline with pin assignment. The name states nothing about manufacturer or source equipment, so confirm the marking on the part. Use it to check pinout before desoldering, interpret meter readings and find a suitable substitute.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @cyberlanelectonik. Enginerys does not host this file.
