Catalogued as a schematic, this 67.4 KB PDF is named for the part 1SS344 and states nothing else about a device or board.

Named purely after 1SS322, this 73.1 KB PDF does not identify any device, board or revision.

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…

Named 244NQ035, this 44.5 KB PDF is indexed under schematics but its title is a component part number from a family of power rectifiers, so treat it as a datasheet.

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.

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…

Listed as a schematic, this compact 47.4 KB PDF is named 80CLQ150, a code that resembles a power semiconductor part number rather than a board number.

Filed as a schematic, this 160 KB PDF carries the bare code 409CNQ135 with no brand, model or revision attached.

The 163 KB PDF named 408CNQ060 sits in the schematic category, yet its name identifies no device or board.

A small 56 KB PDF filed under schematics, named only 40CPQ080. The name looks like a component part code, not a motherboard number, and it states no device, brand or…

A 128 KB PDF carrying the code 30WQ03FN, indexed as a schematic but structured like a discrete semiconductor part number.

Named 28F102, this 116 KB PDF is filed as a schematic but the code points to a 28F-family parallel flash memory device rather than a board.

PDF listed as a schematic for the 28F020, with Intel named as the manufacturer in the file name. The 28F020 is a 2 Mbit parallel flash memory part.

A 128 KB PDF named 25C256, which matches the pattern of a serial memory chip part number, so this is most likely a chip datasheet placed in the schematic category.

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.

PDF reference, 112 KB, for the 24C64 serial EEPROM, a 64 Kbit two-wire memory widely used in consumer and automotive electronics.

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…
