SMD Resistor Calculator

Enter a code, read the resistance value instantly - whether you are repairing a board, sorting components, or learning electronics. All four common SMD coding systems per IEC 60062 in one app, no tables, no guessing.

• 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 code for older boards (e.g. W4 → 68.0 kΩ)
