Enter the SMD code and read the resistor value instantly – free, no ads, offline
⭐ SMD Resistor Calculator – read any resistor code in seconds ⭐ Tap in the code printed on the component and this SMD resistor calculator shows you the exact resistance value instantly. No ads, no sign-up, no detours. ► How it works - Choose the code type in the bottom bar: 3-digit, 4-digit or EIA-96 - Tap the digits printed on your SMD resistor, column by column - The value appears at the top right away in Ω, kΩ and MΩ ► SMD codes this calculator decodes - 3-digit code – e.g. 103 → 10 kΩ - 4-digit code – e.g. 1002 → 10 kΩ - EIA-96 code with multiplier letter – e.g. 01C → 10 kΩ - R notation for small values – e.g. 4R7 → 4.7 Ω ► Who this SMD calculator is for - Electronics hobbyists, makers and DIY builders - Repair technicians checking tiny SMD parts on a board - Students and apprentices in electronics and electrical engineering - PCB designers, prototypers and lab engineers - Anyone who needs to identify an unlabelled SMD resistor fast ► Why this app - Completely free - No advertising - Works offline – no internet connection needed - No account, no registration, no tracking - Tiny download, opens instantly - Light and dark mode - Clean interface with zero distraction ► SMD resistor codes explained in short Unlike through-hole parts with colour rings, an SMD resistor carries a short printed number code. On three- and four-digit codes the first digits are the value and the last digit is the number of zeros. The EIA-96 system instead uses two digits for the value and one letter as the multiplier – an SMD code like 01C simply cannot be read without a lookup table. That table is exactly what this SMD resistor calculator replaces: no code book, no datasheet search, no guessing. Whether you are repairing a board, populating a prototype or checking a reel of parts, calculating an SMD resistor should take one second, not five minutes. ► Feedback Is a code type missing or did something look wrong?
