Electronic Component Codes Pro is a fast, offline electronics reference and calculator for decoding resistor color bands, SMD codes, capacitor and inductor markings, and more. Quickly convert markings to real values, check tolerance and temperature coefficients, and match E-series without manual charts. Ideal for engineers, students, and makers who need a reliable electronics reference app on the bench or in the lab.
Key features:
- Resistor color code and SMD code decoders, including 3, 4, 5, 6-band and EIA-96.
- Capacitor and inductor code calculators with common series and unit conversion.
- Diode and transistor marking lookup with common pinouts and package info.
- Handy tools: Ohm’s Law, LED resistor, series and parallel calculators, power and current.
- Package size reference (0603, 0805, etc.), fast search, favorites, and full offline access.
Designed for speed and accuracy with clear results and practical engineering tools. Keywords: electronics reference app, resistor color code calculator, SMD code lookup, component marking decoder, engineering tools.

How to use:
1. Install and open the app, then choose a component category such as Resistor, SMD, Capacitor, Inductor, or Semiconductor.
2. Optional: create or enable favorites to save frequently used codes and calculators for quick access.
3. Decode components: pick band count and tap colors for resistors, or enter SMD/EIA-96 codes to get value, tolerance, and temperature coefficient. For capacitors or inductors, type the printed code to see capacitance or inductance and preferred E-series.
4. Use engineering tools: open Ohm’s Law, LED resistor, or series and parallel calculators, enter known values, and get instant results with unit conversion.
5. Work faster with extras: search by code or value, save results to Favorites, copy or share values, open datasheet links when available, and customize units and theme for comfortable offline use.
