About this app
Instantly decode the value of any SMD (surface-mount) resistor by entering its printed marking code.
Whether you're repairing a circuit board, sorting components, or learning electronics, this app gives you a fast and reliable way to read all standard SMD resistor markings — no lookup tables, no guesswork.
Supported marking systems:
- 3-digit EIA (e.g. 472 → 4.70 kΩ)
- 4-digit EIA (e.g. 4702 → 47.0 kΩ)
- EIA-96 (e.g. 64S → 45.3 Ω)
- 2-character (e.g. W4 → 68.0 kΩ) — legacy code, common on older boards
All based on the IEC 60062 international standard.
Key Features
- All 4 standard SMD marking systems in one app
- Tap digits and letters — resistance value appears instantly
- Last selection remembered across sessions
- Light & dark mode — follows your system theme automatically
- Works completely offline
- Clean, distraction-free interface
Perfect for electronics engineers, repair technicians, vintage electronics enthusiasts, makers, hobbyists, and students working with SMD components.
Download now and keep a complete SMD reference in your pocket.
