OhmIc — Electronics Toolkit

OhmIc is a fast, offline electronics toolkit for hobbyists, students, makers, technicians and engineers. Decode electronic components, calculate circuit values and check common pinouts instantly — with no account, internet connection or server required. RESISTOR COLOR CODE DECODER Decode resistor color bands quickly and accurately. • 3-band, 4-band, 5-band and 6-band resistor color code decoder • Resistance value, tolerance and temperature coefficient • Reverse resistor lookup — enter a value and get the color bands • SMD resistor code decoder • EIA-96 resistor code decoder CAPACITOR CODE DECODER Identify capacitor markings and values in seconds. • 3-digit capacitor code decoder • Capacitance code lookup • Capacitor tolerance letter codes • Rated voltage code lookup INDUCTOR COLOR CODE Decode common 4-band inductor and choke color codes. ELECTRONICS CALCULATORS • Ohm's law calculator • Resistor series and parallel calculator • Capacitor series and parallel calculator • Inductor series and parallel calculator • LED series resistor calculator Enter the values you know and calculate the missing values instantly. PINOUT REFERENCE Check pin configurations for common transistors, voltage regulators, ICs, development boards and connectors. 100% OFFLINE All calculations and decoding happen directly on your device. No account, no cloud and no waiting. OhmIc is useful in the workshop, classroom, electronics lab, garage or anywhere you need a quick electronics reference. BUILT FOR ACCURACY A wrong component value or pinout can damage hardware. OhmIc focuses on well-documented, unambiguous component information and clearly indicates simplifications where necessary. Available in 27 languages with Light, Dark and System themes.
