ResistorGo - Color Code & SMD

⚡ Identify and encode resistors instantly

ResistorGo is a precise and fast tool for identifying and encoding color-coded and SMD resistors, designed for technicians, professionals, students, and electronics enthusiasts.
Every tool is built around a dedicated keypad. No text boxes, no dropdown lists. Select values in sequence and the keypad adapts to take you to the next step automatically keeping your workflow uninterrupted.

Key Features:
* Band resistor decoder: Identify color-coded resistors using the color keypad. Select bands directly, add or remove them as needed, and get instant results for 3 to 6-band codes.
* SMD resistor decoder: Identify SMD resistors by entering their printed code. Supports 3-digit, 4-digit, and EIA-96 standards.
* Band resistor encoder: Enter any resistance value with optional tolerance and TCR and get the matching band color combination instantly.
* SMD resistor encoder: Enter any resistance value and get all possible codes across every supported standard: 3-digit, 4-digit, and EIA-96.
* History: Every decoded or encoded resistor is saved. Tap any entry to reopen it in the decoder or encoder exactly as you left it.
* Shareable results: Share any result as a link. Links open in a browser without requiring the app installed.
* Multiple themes: Light and dark mode, multiple background colors for the band resistor visualization to improve contrast with foreground band colors.
* Accessibility: Color names displayed on the keypad for colorblind users.
* Broad compatibility: Optimized for phones, tablets, large screens, landscape mode, split-screen, and windowed mode.
* 22 languages supported.
