This application allows you to calculate the value of the resistors based on the color scale, having the option to select 4, 5 and 6 band resistors, it also informs the user if the resistance value is a commercial resistance value or not. . You can also calculate the value of SMD resistors based on the code printed on them, either with 3 or 4 digit codes or with the code belonging to the EIA-96 standard. Finally with this application you can calculate ceramic capacitor values, taking into account the maximum voltage and its tolerance.
