About

AB Resistors is a convenient assistant for calculating and decoding resistors. This app helps you quickly determine resistance using SMD markings or color bands. It's perfect for radio enthusiasts, engineers, students, electronics repair technicians, and anyone who works with electronic components. AB Resistors features: * Decoding 3- and 4-digit SMD markings. * Support for R-codes and the EIA-96 standard. * Calculating resistors with 4, 5, and 6 color bands. * Reverse matching of bands based on a given resistance and tolerance. * Displaying results in Ω, kΩ, MΩ, and GΩ. * Calculating minimum and maximum resistance, taking into account tolerance. * Supporting the temperature coefficient for 6-band resistors. * Calculating series and parallel connections of multiple resistors. * History of confirmed calculations. * Add important results to favorites. * iPhone and iPad support. * Localization in 40 languages. AB Resistors allows you to perform essential calculations quickly, clearly, and without complex formulas. Choose the bar colors or enter the markings—the app will immediately display the resistor value and additional information. All calculations are performed directly on the device. No internet connection is required.
