Active production — no EOL risk on this BOM line
The TPSW336K010R0350: For a BOM cost engineer, this means the part is a safe anchor for current and near-future builds without a single-source sunset risk.
33 µF, 10 V, 350 mOhm ESR — the derating reality
The 350 mOhm ESR sets the ripple current capability: at 100 kHz, the capacitor dissipates I² × 0.35 W, and the 125°C ceiling means the designer must derate the applied voltage and ripple current per the manufacturer's curve, not run at the full 10 V at high temperature. The molded construction (type Molded, series TPS) is the standard KYOCERA AVX platform for general-purpose decoupling and filtering — not the low-ESR automotive or high-reliability COTS+ grade, but the workhorse tantalum for industrial and commercial PCBs where the 350 mOhm ESR is acceptable.
2312 case, size code W — board-fit checklist
Operating temperature range of -55°C to 125°C covers industrial and military ambient conditions — the part is suitable for outdoor telecom, engine-bay electronics, and downhole instrumentation where the board sees the full temperature sweep. The 125°C ceiling is the component body temperature, not the ambient air — derate the applied voltage above 85°C per the TPS series derating guideline.
