Filed as a schematic, this 70.6 KB PDF is named only with the code 1SS319 and gives no device context.

The name 251UL80S is a manufacturer part code rather than a board number, so this 143 KB PDF is likely a power semiconductor datasheet even though it is listed as a…

The name 243NQ gives only a part family prefix with no suffix, so this 45.4 KB PDF probably covers a whole series of power rectifier devices in one datasheet, despite…

Covering the range 5KP5.0 to 5KP110A, this 667 KB PDF is filed as a schematic but is named after a component series rather than a device or board.

Catalogued as a schematic, the 1SR35-400A document is a 92.2 KB PDF with a discrete component style name and the 400A suffix denoting one grade.

A small 105 KB PDF filed under schematics, with a name pointing to the 85C72-82 range. The name gives no device, brand or board number, and the code resembles a…

Catalogued as a schematic, this 61.8 KB PDF is identified only by the code 70u, with no laptop model, board number or revision stated.

Weighing 332 KB, this PDF is titled 25C160, a name that resembles a serial memory part code, so treat it as a chip datasheet rather than a motherboard schematic.

PDF of 55.5 KB titled 30CPQ035, a code following discrete semiconductor numbering, so it is best treated as a datasheet despite the schematic label.

Filed under schematics, this PDF of 309 KB is named only after the 24C64 part number, so it is most likely the datasheet for a 64 Kbit (8 KB) serial EEPROM on the I2C…

Filed as a schematic, this 134 KB PDF is named for the 9AF40 and 9AF60 parts, two variants in one document.
