Reference
Essential look-up pages: symbols, color codes, SMD markings, package and wiring codes.
- Schematic symbols reference — common IEC / ANSI symbols for resistors, capacitors, diodes, transistors, op-amps and more.
- Component marking codes — resistor color codes, capacitor markings, diode series codes and other quick tables.
- SMD markings — decoding 2–3 character codes on SMD transistors, diodes and ICs.
- Package and case codes — TO, SOT, SOD, SOIC, TSSOP, QFN, LQFP and other package names with basic dimensions.
- Wire and cable codes — AWG cross-sections, insulation ratings and common color conventions.
