Parts and Bins

Parts, bins and matching

Parts are part numbers (optionally with a manufacturer). Bins are groups of one part: a lot, a bag, a date code. Tag readings into them from the Identify tab, a reading's page, or in bulk from History.

The Parts tab lists parts with their reading and bin counts. A part or bin page shows, for every headline parameter (hFE, hFE (DCA55), Vbe, leakage, Vgs(th), Idss, Vf, Icbo…):

• a statistics table: n, min, p5, p25, median, p75, p95, max, mean and σ;
• a histogram for the selected parameter;
• the member readings sorted by that parameter — tap one to see its closest matches, useful for matching transistor pairs.

History filters by type, part, bin, date, text, untagged and starred, supports bulk tagging and deletion, and exports CSV. A bin page exports its own CSV.
