Littelfuse Inc /de
A maker of circuit protection and sensing components, Littelfuse produces the fuses, power semiconductors, and switches that keep data centers, vehicles, and power grids running safely. The company was born in 1927 when engineer Edward Sundt, frustrated by test meters burning out during electrical work, invented a small fast-acting fuse and sold his car to fund the business. He wanted to call it "Little Fuse," but was denied the trademark as too generic—so he cleverly misspelled it as "Littelfuse" instead.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last year: -98.6K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
