Sizing this tantalum for 24 V and 48 V rails
The 50 V rating provides a 2× derating margin on a 24 V rail and 1.04× on a 48 V bus — the 48 V case is tight, so confirm the steady-state voltage never exceeds 50 V at the capacitor terminals. With a 6.6 Ohm ESR, this part handles ripple current in decoupling applications but self-heats under high AC content.
Package fit and footprint check
The 1206 (3216 Metric) case measures 3.20 mm × 1.60 mm with a seated height of 1.80 mm. The manufacturer size code A matches the standard 1206 tantalum footprint — no pad geometry change needed from a generic 1206 tantalum land pattern. Surface-mount assembly; the molded case is compatible with reflow soldering. The ±20% tolerance is typical for tantalum capacitors and acceptable for bulk decoupling, but for timing or filter circuits where capacitance accuracy matters, a tighter tolerance part is needed.
