CHICAGO, June 3, 2026, 03:23 CDT
Littelfuse Inc. shares jumped Tuesday, closing at a new 52-week high as the AI data-center product debut landed. The stock, which trades on the Nasdaq, finished at around $487.90, up 5.3%. It hit $489.60 during the day. Investors have pushed the shares higher since its first-quarter earnings.
Littelfuse is making its pitch now as it wants to prove its circuit-protection products belong in new higher-power data center projects, not just in industrial or automotive use. Regular U.S. trading opens later Wednesday; Nasdaq’s standard hours run 9:30 a.m. to 4 p.m. ET, with pre-market trading from 4 a.m. ET.
Littelfuse, Inc. said Tuesday it launched its NANO² Surface-Mount 708 Series Fuse, targeting 48-volt DC power setups in AI servers, hyperscale data centers, and dense power distribution. The fuse has a 14,000-amp interrupting rating at 80 VDC. That measures how much fault current the fuse can safely handle.
Daniel Wang, senior director of product management for over-current passives at Littelfuse, said the new fuse lets designers switch from older through-hole or bolt-down types to surface-mount tech. Wang said that allows for automated manufacturing, raises productivity and brings down total system costs.
Littelfuse announced the new product less than a month after posting first-quarter net sales of $657 million, up 19% from the same period a year ago. The company said organic growth, excluding acquisitions and currency, was 9%. Adjusted diluted EPS was $3.31. Adjusted EBITDA margin increased to 22.9%.
Littelfuse’s latest results showed data centers already driving growth in the numbers. The company reported a 45% jump in industrial sales for the quarter, lifted by demand from grid, utility infrastructure and data centers. The Basler acquisition made up 39 percentage points of that industrial segment growth. Electronics sales were up 18%, with gains from passive product demand and higher protection semiconductor volumes.
Littelfuse CEO Greg Henderson said it was a “strong start to the year” and added that “demand strength remains broad based.” Littelfuse is looking for second-quarter net sales between $690 million and $710 million, with adjusted diluted EPS in the $3.65 to $3.85 range. The company set its $0.75-per-share dividend for June 4, with a record date of May 21. Littelfuse Investor Relations
Analysts are looking for more. Latest Investing.com data puts the average 12-month price target at $477.50. Targets range from $390 up to $520. Needham, Oppenheimer, and Baird kept Buy ratings in May. But the average price target is still just under where shares last traded.
Several electronics and electrical-components stocks traded higher as well. Amphenol was last up 1.5%, TE Connectivity added 1.7%, and Vishay Intertechnology climbed 11.6%, latest quotes showed. That sector strength helped Littelfuse, so the gain wasn’t only a company story.
But investors now seem to be paying up for smooth execution. If demand for AI servers drops, or if commodity prices or tariffs increase, or if Basler synergies are slow to show, Littelfuse might have a hard time holding onto the earnings gains now expected in the stock. Company filings point to product demand, capacity, FX swings, commodity costs, tariff shifts and integration of acquisitions as risks.
Shares sit near highs as the company launches a product linked to AI power systems. Orders have been strong so far, and management is aiming for a longer streak of growth. The focus shifts to Wednesday’s session to see if the stock can hang on to Tuesday’s rally once early buying settles.
