330 µF at 4 V — bulk decoupling anchor
The TAJF337M004RNJ: 330 µF capacitance at a 4 V rated voltage places this part in the bulk decoupling category for low-voltage rails — supply hold-up on a mixed-signal board where the transient current draw is moderate.
Wide temperature range and ESR floor
For a 4 V rail, the maximum ripple current is limited by self-heating — check the derating curve in the TAJ series datasheet for the exact limit at 125°C.
Size F case — 2312 footprint
Package / Case 2312 (6032 Metric), size code F, measures 6.00 mm x 3.20 mm x 2.00 mm seated height. The molded case is a standard tantalum outline; the 2.00 mm height leaves clearance under a low-profile enclosure or adjacent PCB.
