33 µF, 6.3 V, 1206 — the bulk decoupling anchor
Temperature range and the 2000-hour limit
ESR and ripple-current reality
At 33 µF and 2.2 Ω, the impedance at 100 kHz is dominated by the ESR, so the capacitor behaves like a resistor at the switching frequency — useful for damping high-frequency noise but not for low-ESR bulk storage.
