Circuit Inputs

VIN, VOUT, frequency and component values are calculated in your browser. The calculator does not send circuit inputs to a server or save them in cookies or browser storage. Copy results writes the result to your device clipboard.

Your language preference is saved on this device. Circuit inputs are not saved.

Visit Counts & Browser Storage

We count visits by country. Reloads or returns in the same tab within 30 minutes count as one visit. A random identifier in browser session storage reduces duplicates; the server retains an expiring hash of that identifier and country totals. The app does not store IP addresses, precise locations or circuit inputs. Country is an approximate location supplied by the hosting network; unavailable locations are counted as unknown. Counts are not exact unique people and may be affected by browser settings and automated traffic.

Site Access

When pages and files are downloaded, the hosting provider may process connection information such as IP addresses. Not transmitting circuit inputs does not mean that no network information is processed. This site uses HTTPS.
