22 µF, 25 V — 2917 case, 900 mOhm ESR
Its 900 mOhm ESR at 25 °C sets the ripple-current capability and self-heating — for a 100 kHz buck output cap, the ripple current stays under 300 mA RMS to keep internal temperature rise below 10 °C. The 2917 (7343 Metric) case, size code D, is a common footprint for 22 µF/25 V tantalum caps — the 7.30 mm x 4.30 mm land pattern fits standard reflow profiles.
At 125 °C the voltage derating per MIL-PRF-55365 applies: for 25 V rated, a 50 % derating (12.5 V applied) is standard for long-life mission reliability.
Availability confirmed at RFQ.
