22 µF, 50 V, ±20% — the BOM-fit check
The 50 V rating gives headroom for 12 V, 24 V, and even 48 V rails, keeping the derating margin above the 80 % rule for tantalum reliability.
Full temperature range and 2000-hour life
The operating temperature spans -55 to 125°C, covering industrial, automotive under-hood, and military/aerospace environments.
ESR and ripple current at 100 kHz
For a typical switching regulator output, the ripple current squared times ESR gives the internal temperature rise; budget this against the 125°C ambient to stay within the lifetime rating.
V case code — 2924 footprint
The V case code corresponds to the 2924 (7361 metric) package: 7.30 mm x 6.10 mm footprint with a seated height of 3.75 mm max. The land pattern matches the standard 2924 tantalum pad layout — confirm the pad dimensions against your PCB footprint library.
