The 1411 (3528 Metric) package footprint — 3.50 mm × 2.80 mm with a seated height of 2.10 mm — fits standard low-profile power decoupling layouts on multilayer PCBs.
Voltage derating and BOM fit
At 4 V rated, the recommended derating for a tantalum capacitor is 50 % — so this part is suited for rails up to 2 V DC. The 33 µF value provides bulk decoupling for low-voltage regulators, power-management ICs, or filtering on 1.8 V and 2.5 V supply lines where ESR is less critical than capacitance density.
