Solver for optimal three-resistor voltage dividers using E24 and/or E96 series resistor values.

High Voltage Divider Calculator

This program finds three-resistor voltage dividers created from real-world resistor values (EIA E24 and/or E96) with divider ratios closest to some target. There are two upper resistors in the divider circuit to provide current limiting even if one of them shorts. Resistor tolerance and overall divider string resistance are taken into account. The calculator is a single .html file with inline Javascript.
