33 µF bulk decoupling for 3.3 V and 5 V rails
The TPSC336M016R0225: The 225 mOhm ESR sets the ripple current handling: at 100 kHz the cap can carry roughly 1.2 A RMS before self-heating becomes a concern, which is adequate for most point-of-load filters. The ±20% tolerance is standard for tantalum electrolytics — adequate for output filtering on a buck converter but not for a timing circuit where C tolerance drives the RC time constant.
Active production — no EOL pressure on this BOM line
Listed as Active by KYOCERA AVX — no last-time-buy notice, no end-of-life watch. The TPS series is a mature, widely stocked line; availability is confirmed at RFQ against the BOM quantity.
Molded case, 2312 footprint, full military temp range
The molded case is a standard tantalum construction with a flat top and rounded edges — it reflows well on a standard 2312 (6032 Metric) land pattern and the 2.80 mm seated height fits most board stack-ups without clearance issues. The -55 to +125 °C operating range covers military, avionics, and downhole applications; the capacitor's ESR and capacitance stay within datasheet limits across the full band.
