At only 24.2 KB, the 2SC3989 PDF is a compact document, probably a short datasheet or summary page for this JIS-numbered NPN bipolar transistor despite being indexed as…

The file 70mtkb is a 73.3 KB PDF filed as a schematic, and its name provides no brand, model or PCB revision.

Very short 20.1 KB PDF for the part 27C256-12A, catalogued as a schematic. The number belongs to the 27C EPROM family, and the -12 suffix normally reflects the…

Brief 28.4 KB PDF for the 2SK2864, indexed as a schematic; its small size points to a one or two page datasheet or summary. The name gives only the part number.

Small 33.2 KB PDF covering the 2SK1478, written in lowercase in the original name. The 2SK prefix belongs to the Japanese semiconductor designation for N-channel…

A compact 19.1 KB PDF for the 2SA1580, small enough that it is probably a one- or two-page summary sheet. No other details are present in the name.

Phone specification document in a 10.1 MB PDF; the name states only that it contains specifications and gives no brand or model, so the target device must be identified…

Small 67.6 KB PDF filed under BQ24727, a Texas Instruments battery charger controller found on many laptop motherboards.

At just 31.4 KB, the PDF named 2SJ499 is probably a short datasheet or summary sheet, even though it is filed as a schematic.

Compact datasheet, 14.5 KB in PDF form, for the part numbered 2N2955 according to the file name.

Short PDF of only 19.4 KB covering the 1SV298H, the H suffix marking a variant of the base 1SV298 part.

A compact 116 KB PDF named after the BQ24737, a Texas Instruments notebook battery charger controller.

A small 40.3 KB PDF for the 2SK2867, filed as a schematic; the modest size suggests a short datasheet or summary page. The name contains nothing but the part number.

Short PDF of 17.5 KB titled 23SC4428, catalogued under schematics. The name gives only a part number, and its 4428 suffix resembles that of a known smart-card memory…

Schematic for a mosque mixer, the Indonesian name Mixer Masjid, model Master Box X6, provided as a 585 KB PDF despite the doubled extension in the original name.

A compact 44.5 KB PDF labelled 2SJ520 and catalogued as a schematic. Because 2SJ is the JIS prefix for P-channel FETs, the document is best treated as a short datasheet…
