A 1.78 MB PDF datasheet for the tiny2313, consistent with the Atmel AVR ATtiny2313 microcontroller.

Hardware datasheet for the u-blox NEO-6 series GPS modules, document reference GPS.G6-HW-09005 per the file name.

Datasheet for the L298, a dual full-bridge driver from ST used to run DC motors, relays and stepper motors at up to several amperes total.

PDF schematic for the HP nx6320 laptop, around 1 MB in size. The name gives no motherboard number or revision, so compare the board identifier printed on the PCB before…

Schematic set for the HP nx900 laptop, distributed as a 1.01 MB PDF. The file name identifies only the model and provides no board number or revision, so confirm the…

Schematic PDF named only CD731a, about 526 KB, with no brand, model or revision information in the name.

Schematic in PDF format for a GTX 750 Ti graphics card, based on the board code P2010-B01, which follows NVIDIA's reference PCB numbering.

Datasheet for the IRF510 N-channel MOSFET, a 97.7 KB PDF. The document should cover ratings, transfer and output characteristics, capacitances and the TO-220 pinout.

Datasheet PDF for the BD234, only 49.2 KB and indexed as a schematic. The BD234 is a medium-power PNP transistor in a plastic package, commonly paired with a…

A 53.4 KB PDF covering the 2SD2614 transistor, catalogued as a schematic although the name points to a single-part datasheet.

The 2SD2648 is covered by this 29.0 KB PDF, indexed as a schematic but in practice a single-device reference.

Component reference for the 5LP02C, a 42.3 KB PDF that the index lists as a schematic. The name carries just the part code, where the LP letters appear to mark a…

Reference PDF of 27.6 KB for the component 5HP01S, filed among schematics although it describes one discrete part.

A 28.0 KB PDF classed as a schematic whose name, 3LP01C, reads as a component part code ending in C. The file name gives no device, board number or manufacturer.

PDF of 41.6 KB, catalogued as a schematic and named 3LN02M, which looks like a semiconductor part number with an M suffix rather than a board code.

PDF of 27.9 KB filed as a schematic under the code 3LN01S, which reads as a discrete component part number with an S suffix.

The 2SD1908 transistor is documented in this 85.8 KB PDF, which the index files as a schematic, although a JIS part number like this normally indicates a datasheet.

A 68.3 KB PDF bearing the name 2SD2324, a Japanese JIS designation for an NPN transistor, since 2SD marks NPN low-frequency devices.

A 30.6 KB PDF labelled with the JIS part number 2SK3488 and filed in the schematic category, though the content should be a component datasheet.

Reference sheet for the 2SK2917 N-channel field-effect transistor, stored as a 423 KB PDF and listed in the schematic category.

Datasheet PDF of 413 KB for the 2SK2866 transistor, catalogued under the schematic type. Only the part number is stated in the name.

A very small PDF of 23.8 KB named for the 2SK2797, filed under schematics. The 2SK prefix follows the JIS naming convention for N-channel field-effect transistors, so…

PDF of 140 KB for the 2SK2739 with an unexplained 1-5 suffix, which may indicate an edition or page count rather than a different part.

A 116 KB PDF for the 2SK2731 bearing a 1-5 suffix that the name does not explain, perhaps an edition marker.

Compact 23.1 KB PDF named only with the part number 2SK2277. Because 2SK is the JIS prefix for N-channel FETs, the schematic category here most likely holds a short…

Short 23.7 KB PDF for the 2SK2014, a part number from the JIS 2SK series used for N-channel FETs.

Indexed as a schematic, this 112 KB PDF carries just the name 2SK1454, a JIS-style code for an N-channel field-effect transistor.

The file name gives nothing beyond 2SJ562, a JIS-style designation; the 2SJ prefix denotes a P-channel field-effect transistor.

Part reference 2SJ508 is all the name provides for this 136 KB PDF, categorised as a schematic.

Component document for the 2SJ501 in a 239 KB PDF, labelled in the catalogue as a schematic.

A 105 KB PDF for the 2SJ421, catalogued as a schematic but in practice a component datasheet, since the 2SJ prefix in the Japanese JIS numbering system marks a P-channel…

Listed under schematics, this 94.5 KB PDF carries only the designation 2SJ276. Under the JIS system the 2SJ prefix belongs to P-channel FETs, so the file is almost…

Bearing only the part code 2SJ264, this 101 KB PDF relates to a P-channel FET, as the JIS 2SJ prefix designates that transistor type.
