Preview

  • Page 2: the resistor colour code table with a swatch for each of the 13 colours, and 4-band and 5-band reading guides
  • Page 6: capacitor codes, with common three-digit codes in pF, nF and µF, tolerance letters and voltage codes
  • Page 7: 2N2222 pinouts for the P2N2222A, PN2222A, TO-18 2N2222A and SOT-23 MMBT2222A
  • Page 10: Ohm’s law, power and voltage divider formulas, each with a worked example

The previews carry a "Preview" watermark. The PDF you download has none, and its text stays sharp at any zoom.

What’s inside

  • Resistor colour code

    All 13 colours to IEC 60062 with digit, multiplier, tolerance and temperature coefficient, and how to read 4-band and 5-band parts.

  • E6, E12 and E24 values

    One table, lined up so you can see which values each series shares.

  • E96 values and EIA-96 codes

    All 96 values with their two-digit index, and the multiplier letters.

  • SMD resistor codes

    Three-digit, four-digit, R as the decimal point and zero-ohm jumpers, with decoded examples.

  • Capacitor codes

    The three-digit code with the common values in pF, nF and µF, tolerance letters, voltage codes and the EIA-198 letters.

  • Transistor pinouts

    P2N2222A, PN2222A, 2N2222A (TO-18), MMBT2222A, BC547 and 2N3904, each drawn from the maker’s datasheet page.

  • 8051 DIP-40 pinout

    All 40 pins with their second functions, as the AT89S52 datasheet prints them.

  • Formulas

    Ohm’s law, power, series and parallel resistors, the voltage divider, RC timing, the LED resistor and the LM317, each with a worked example.

Who it is for

Students, hobbyists and repair technicians who want the numbers on paper next to the soldering iron instead of on a phone screen.

Everything in the pack is also free on the site, spread across these pages. The pack puts it on paper in one place:
