33 µF at 10 V – the bulk-capacitor decision
The TAJB336K010A: The 33 µF capacitance at 10 V rated voltage covers the bulk-decoupling need for a 3.3 V or 5 V rail that sees a 10 V input transient — the 10 V rating gives headroom above the rail without oversizing to 16 V. 1.8 Ohm ESR is the main loss term: at 100 kHz the impedance is dominated by this resistance, so ripple current capability is ESR-limited rather than capacitance-limited. For a 500 mA load transient the self-heating stays under 10 °C if the PCB copper area is adequate.
Full military temperature range in a standard TAJ case
Molded 1411 (3528 Metric) case, size code B, 3.50 mm x 2.80 mm footprint, seated height 2.10 mm max — fits the standard 1210 pad layout used across the industry for 33 µF/10 V tantalum replacements.
