About SMD Resistor Calculator

Decode and encode surface mount (SMD) resistors instantly with this modern, highly precise, and visually stunning SMD Resistor Code Calculator.

Designed for electrical engineers, technicians, electronics hobbyists, DIYers, and students, this app simplifies component value calculation with state-of-the-art interactive tools and tables.

★ KEY FEATURES ★

• INTERACTIVE 3D PREVIEW
Type in any code and watch the high-definition, custom-painted SMD resistor chip update in real-time. It displays the correct colors, terminal leads, and matching monospace text so you know exactly what the physical board component looks like.

• SMART CUSTOM KEYPAD
Forget typing errors. The app features a custom alphanumeric keyboard that automatically enables or disables keys dynamically based on what you are typing. It guides you to enter only valid, industry-standard codes.

• FULL Marking Standard Decoders:
- 3-Digit Codes (±5% Tolerance, standard E24 series)
- 4-Digit Codes (±1% Tolerance, E96 series precision)
- Decimal "R" Codes (e.g. 4R7 = 4.7Ω, R22 = 0.22Ω)
- EIA-96 Codes (e.g. 01C = 10kΩ, 53B = 3.48kΩ)
- Current-Sensing Milliohm Codes (e.g. 2L5 = 2.5mΩ, 0M50 = 0.50mΩ)

• VALUE-TO-CODE ENCODER
Need a specific resistance? Enter your target value (e.g., 4.7 kΩ) and the app will generate all corresponding markings across standard systems (3-digit, 4-digit, and EIA-96) along with mini visual preview chips.

• PERSISTENT HISTORY & FAVORITES
Log recent decodes or pin your most-used resistor values to favorites for quick, single-tap access later.

• INTEGRATED EIA-96 LOOKUP TABLE
A fully searchable scrollable reference table for the 96 base values (01 to 96) in the E96 series, making manual decoding a breeze.

• COLLAPSIBLE KEYPAD
Easily collapse the custom keypad in decoder mode to expand the visible details card and read complex multiplier calculations or reference data without scrolling.

★ PREMIUM DESIGN & UX ★
Experience a dark cyberpunk theme designed for late-night soldering and bench lab work. Featuring crisp neon cyan, emerald green highlights, smooth animations, and light impact haptic feedback. Fully optimized to consume low battery.
