330 µF bulk capacitance with low ESR for power rail smoothing
The TPSE337M016R0200: The 200 mOhm ESR at 100 kHz is the figure that governs ripple current handling — a lower ESR means the capacitor runs cooler under AC ripple, which directly extends service life in switching-regulator output filters. The ±20% tolerance is standard for tantalum electrolytics; the actual capacitance at 16 V bias will sit closer to the nominal value than the tolerance suggests.
Active lifecycle — no end-of-life risk for new designs
The molded construction (E case code) means the capacitor body is encapsulated in epoxy, providing mechanical rigidity and moisture resistance suitable for reflow soldering. The 2917 footprint is shared across multiple tantalum suppliers, making second-sourcing straightforward at the board level.
Decoupling and hold-up duty in power distribution
The 200 mOhm ESR limits the voltage droop during the first few microseconds of a load transient — a figure worth checking against the regulator's transient response spec. The molded body has no conformal-coating compatibility issues; standard reflow profiles for tantalum capacitors apply.
