A GPU sitting idle draws a fraction of what it draws one clock later. On a Blackwell-class accelerator running at roughly 1000 W, the core rail sits near 0.85 to 0.9 V while the current swings across several hundred amperes as tensor cores spin up. The regulator cannot follow that edge. It is far from the [...]
Capacitor supply problems are rarely created by the purchasing team. They are created on the schematic, months or years before anyone needs a second source. A part that looks interchangeable on paper can still turn out to be impossible to replace. The reasons are mundane: a footprint only one factory builds, a tolerance window drawn at [...]
A purchase order for high-capacitance MLCCs placed this month may not ship until the second quarter of 2027. Constrained parts that used to arrive in six to eight weeks now quote at four months or longer, and allocation has become an ordinary word in distributor conversations. When the schedule slips, the question from the production floor [...]
Capacitor lead times in 2026 have stretched from weeks to months, and on AI-grade MLCC a ten-month quote is no longer unusual. Ordering more will not fix that. The buyers holding their schedules together are the ones who know which lines on the bill of materials have to be locked, commit on those before allocation begins, [...]
Selecting a capacitor for an AI server power stage starts with three numbers: the rail's voltage, its power or ripple current, and the ambient temperature it runs in. Once you have those, match the rail's role to the right capacitor type—aluminum electrolytic for 380 V rectifier and 48 V intermediate rails, polymer or MLCC for low-voltage [...]
