Does PartGenie include the complete KUU catalog?

Yes. PartGenie provides a searchable manufacturer catalog when source catalog data is available; this hub is the intelligence and navigation layer that summarizes KUU product families, sourcing risks and decision paths.

How should engineers compare KUU protection devices with alternatives?

Compare the intended function first, then verify voltage rating, surge waveform, clamping performance, capacitance, leakage, package, polarity and thermal or derating data. Treat cross-vendor options as functional alternatives until the design review confirms fit.

Is KUU mainly a power-management or circuit-protection brand?

The official category list spans both areas: circuit protection parts such as ESD, TVS, GDT, MOV, PPTC and TSS devices, plus MOSFETs, Schottky diodes, NTC thermistors, LDO regulators and DC-DC power-management ICs.
