It's not just components, buried in the industrial stuff are things like.
All possible types of PCB making machines, including laser cutters
85151100 Electric soldering irons and guns
85151900 Electric brazing or soldering machines and apparatus, other than soldering irons and guns
85351000 Fuses, for a voltage exceeding 1,000 V
85361000 Fuses, for a voltage not exceeding 1,000 V
85362000 Automatic circuit breakers, for a voltage not exceeding 1,000 V
85364100 Relays for switching, protecting or making connections to or in electrical circuits, for a voltage not exceeding 60 V
85364900 Relays for switching, protecting or making connections to or in electrical circuits, for a voltage exceeding 60 but not exceeding 1,000 V
85366940 Connectors: coaxial, cylindrical multicontact, rack and panel, printed circuit, ribbon or flat cable, for a voltage not exceeding 1,000 V
85369040 Electrical terminals, electrical splicers and electrical couplings, wafer probers, for a voltage not exceeding 1,000 V
enameled copper wire, and no doubt a ton more stuff.
It's not just the tariffs, that will make things cost more, it's the huge mess implementing it. I'd expect companies to pass on the cost of implementing all this.
