Molded tantalum for low-voltage rails
Its 200 mOhm ESR keeps ripple heating low in DC-DC output filtering and bulk decoupling for 3.3 V and 1.8 V rails.
Package fit and board layout
Listed for both 1411 (3528 Metric) and 1210 footprints, this part fits standard SMD pads with a 3.50 mm x 2.80 mm body and 2.10 mm seated height. The dual footprint listing simplifies alternate-sourcing validation — the same reel works on either land pattern. Size code B (EIA 3528-21) is a common tantalum footprint; the 200 mOhm ESR is specified at 100 kHz, so the capacitor handles the ripple current from a 500 kHz buck converter without excessive self-heating.
