330 µF bulk cap with 50 mOhm ESR for power rail filtering
The KYOCERA AVX TPSE337K010T0050V is a TPS series molded tantalum capacitor offering 330 µF capacitance at a rated voltage of 10 V, with a low equivalent series resistance of 50 mOhm at 100 kHz. The 50 mOhm ESR keeps self-heating low under ripple current, which is critical in high-frequency switching regulators — the impedance at 100 kHz is the figure that determines filter attenuation, not the DC resistance.
Rated for -55°C to 125°C operating temperature, this capacitor spans industrial and military temperature grades without derating at the high end. The ±10% tolerance is typical for tantalum polymer capacitors and adequate for decoupling and filtering applications where the exact capacitance is less critical than the ESR and voltage rating.
Active lifecycle — no obsolescence risk for new designs
This eliminates the single-source risk that haunts older tantalum part numbers — the TPS series is widely stocked across distribution channels, and the 2917 footprint is a commodity size that multiple manufacturers cover.
