PDF for the KA4558, a dual operational amplifier in the KA series, equivalent in function to the familiar 4558 dual op amp, size 121 KB.

PDF reference on the 2SC4517 transistor, the name noting it as NPN; the file is 26.9 KB and indexed as a schematic.

Catalogued as a schematic, this 27.2 KB PDF carries only the code 3LP01SS, which looks like a component part number with a two-letter SS suffix.

The name 2sd1455 refers to a JIS-registered NPN transistor, and this 53.0 KB PDF is most likely its manufacturer datasheet, although the index lists it as a schematic.

Component sheet for the 2SK2886 transistor, delivered as a 424 KB PDF and filed in the schematic category. The name carries only the part number.
