330 µF, 10 V, 50 mOhm — bulk decoupling on a tight rail
The TPSE337K010R0050 is a 330 µF, 10 V molded tantalum capacitor from the TPS series, housed in a 2917 (7343 Metric) case with a 50 mOhm ESR. The ±10% tolerance is standard for tantalum electrolytics; the capacitance holds well over the -55°C to 125°C range, so you don't lose margin at temperature extremes.
Active lifecycle — no end-of-life watch needed
This part carries an Active lifecycle status from KYOCERA AVX. The TPS series is a broad tantalum platform; the 50 mOhm ESR variant is common enough that second-sourcing or alternate capacitance/voltage combinations (e.g., 220 µF at 16 V in the same case) are straightforward if a BOM change is needed later.
Sourcing and fit for the BOM
The 2917 footprint is standard across multiple manufacturers (Kemet, Vishay, Panasonic), so a drop-in alternative exists if the KYOCERA AVX line has lead-time pressure.
