PRIVACY & LIMITATIONS

Circuit targets stay local. No EDA is connected.

Target resistance, preferred series, range, tolerance, and DC voltage participate only in the current-page search. ResistorNet does not read schematics, PCBs, BOMs, or inventory systems, and it sends nothing to purchasing or design tools.

Ideal DC networks, not component-rating validation

The tool builds two-resistor series/parallel candidates from at most 650 IEC preferred values and searches nearby combinations for three-resistor series, parallel, and mixed topologies, ranking absolute ppm, part count, and peak dissipation. The tolerance envelope assumes the same nominal percentage for every positive resistance; power uses ideal DC steady state. It does not cover actual stock, mixed tolerances, tempco, noise, voltage coefficient, parasitics, pulses or surges, PCB thermal conditions, creepage, or fail-safe behavior.

BOM targets and voltage may be design data

Refreshing or closing discards inputs. CSV contains topology, R1/R2/R3, equivalent resistance, error, and peak dissipation; reports and optional local checkpoints read the visible result summary. Targets, voltages, and candidate BOMs for unreleased circuits may be sensitive, so review them before sharing.

Advertising and local preferences

This page uses Google AdSense Auto Ads. Google may use cookies or similar technologies under its policies. .miluland.com domain cookies sync language, theme, high contrast, a six-item recent-tools list, and up to 16 favorite tool IDs across MiluLand sites. These values never contain inputs, files, or results; the current site also keeps a local compatibility copy.

Local report studio

The report studio reads only the workbench’s currently visible result summary for local preview, Markdown copy, JSON download, printing, and a SHA-256 fingerprint. It never reads input controls or original files and is not persisted unless you choose to download it.

Optional local checkpoints

Only when you explicitly choose Save does the tool write the visible result summary, time, and optional short label to this site’s browser storage, up to five entries. Imported files and input-control contents are never stored; you can export, restore same-tool checkpoints, or clear them at any time. Imports are limited to 128KB and validate the tool, timestamp, summary, and label of up to 80 characters.
