Bulk capacitance for a 2.5 V rail — what the ratings mean
The 2200 µF capacitance at 2.5 V provides significant energy storage for a low-voltage rail — think decoupling a 1.8 V or 2.5 V core supply on a processor or FPGA, where the bulk capacitance handles transient load steps before the VRM loop responds. For a typical 100 kHz switching ripple, the self-heating from I²R losses limits the AC current the capacitor can sustain; the buyer should check the ripple current rating in the full datasheet against the application's ripple amplitude. Operating temperature spans -55 to 125 °C, the military-grade range. At 125 °C the leakage current rises and the capacitance may drift — the derating curve in the datasheet shows the safe voltage at elevated temperature.
Package and footprint — 2924 (7361 Metric) size V
Housed in a 2924 (7361 Metric) surface-mount package, size code V, with dimensions 7.30 mm x 6.10 mm and a seated height of 3.75 mm. This is a larger case size for a tantalum — the 2200 µF density at 2.5 V requires the volume. On the PCB, the pad pattern should follow the manufacturer's recommended land pattern for the V case to ensure proper solder fillet and mechanical stability.
