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.
← Back to toolLocal 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.
Analytics and your choices
Google Analytics measures page visits and tool openings. Visitors in the EEA, UK, Switzerland, mainland China, Canada, South Korea, and Türkiye are asked first; other identified regions start automatically. A previous refusal, GPC, or Do Not Track takes precedence. Tools work with either choice.
We use same-site Cloudflare connection information to determine the country or region, not your language, and do not save the IP address in the lookup. If the lookup fails, the Google tag still starts with regional consent defaults: analytics cookies in consent-required regions await permission, while Google may receive basic cookieless signals. Automatic startup is not recorded as your explicit consent.
Files, filenames, tool inputs, search terms, URL parameters, fragments, and results are excluded. Page names use fixed paths and referrers contain only the source site. Google processes visit identifiers and technical browser information. Enhanced measurement, Google signals, and ad-personalization measurement are disabled.
Turn analytics on or off through Privacy & analytics in the footer. Explicit choices are shared across enabled pages in a .miluland.com cookie for up to 180 days; automatic startup does not save an accepted choice. Turning it off stops this integration and clears accessible GA cookies. Advertising uses separate consent settings.
