330 µF, 10 V tantalum — the ESR is the selection driver
The TPSV337K010R0040: The 40 mΩ ESR (Equivalent Series Resistance) is the headline parameter — it determines the ripple current capability and the self-heating under AC load. For a 330 µF part at 10 V, a 40 mΩ ESR means the capacitor can handle higher ripple current than a standard-grade tantalum of the same capacitance, making it suitable for decoupling in DC-DC converter outputs or as bulk storage in power rails where low impedance matters.
The V size code maps to this case dimension.
No official successor or cross-reference is recorded for this part number. The TPS series includes multiple voltage/capacitance variants in the same case size, but a direct pin-compatible substitute would require matching the 330 µF / 10 V / 40 mΩ ESR triplet.
