The TPSD337K006R0050: The ±10% tolerance is tighter than the ±20% common on many general-purpose tantalums, so the actual capacitance at the rail stays closer to 330 µF across the production spread — useful when the downstream regulator's stability or the hold-up time budget depends on a minimum capacitance value.
Case, temperature grade, and lifecycle
The molded case is the conventional MnO2 tantalum construction — not a polymer cathode, so the voltage derating guidelines for MnO2 tantalums (typically 50% derating on the rated voltage) apply here. Rated for -55°C to 125°C operation, covering the full industrial and military temperature range. At 125°C the voltage rating may be derated per the standard tantalum derating curve — check the application note for the exact voltage vs temperature profile. This is a current-production order code, not a phase-out or last-time-buy part.
Sourcing and BOM fit
The TPSD337K006R0050 is an active, standard-series tantalum cap from KYOCERA AVX. The 2917 footprint is shared across multiple manufacturers (Kemet, Vishay, etc.), so a parametric alternative with the same case code, capacitance, voltage, and ESR band can be sourced if the BOM needs a second source — confirm the ESR and tolerance match before substituting.
