About

Resistor Value Calculator is a comprehensive electronics engineering tool for engineers, hobbyists, and students. Features: • Color Band to Value Calculator — supports 3, 4, 5, and 6-band resistors with real-time visualization and smart auto-sequence input. • Reverse Lookup — enter a resistance value to find matching color band combinations. • SMD Code Calculator — decode 3-digit, 4-digit, and EIA-96 SMD resistor codes. • LED Current-Limiting Resistor Calculator — compute the correct resistor for LEDs with series/parallel configurations and common LED presets. • Series/Parallel Network Calculator — calculate equivalent resistance for series and parallel resistor networks. • E-Series Standard Preferred Values Table — browse IEC 60063 E6 through E192 series with search. • Save and export resistor presets to CSV from local history. • Dark and light theme support. All calculations follow IEC 60063, EIA-96, and standard E24-E192 conventions. No account or login required — works entirely offline on your device.
