33 µF, 16 V, 300 mOhm ESR — parametric fit for bulk decoupling
The TPSY336M016R0300: The 300 mOhm ESR is the spec that governs ripple handling and transient response — at 100 kHz, the impedance is dominated by this resistance, not the capacitive reactance, so the part's ability to absorb switching noise from a nearby DC-DC converter is directly proportional to the ESR ceiling.
Temperature grade and operating envelope
At the high end, the leakage current and ESR both increase; the 300 mOhm spec is typically measured at 25°C and rises with temperature, so the effective ESR at 125°C is higher than the catalog value. The ±20% tolerance is standard for MnO₂ tantalum capacitors — the capacitance at -55°C can drift down by about 10-15% from the 25°C value, so the effective minimum at cold is around 24 µF, still adequate for most decoupling roles.
Package — 2917 (7343 Metric), size code Y
This is the standard low-profile tantalum footprint for 33 µF at 16 V — the same land pattern as the generic 7343-20 case. The molded construction provides consistent dimensional control for pick-and-place, and the tape-and-reel packaging supports automated assembly. No exposed paddle or thermal pad — the ESR is managed through the internal MnO₂ cathode system, not board-level heatsinking.
Active lifecycle — sourcing posture
No official successor or second-source cross-reference is published — the part is the current standard offering in the TPS series for this capacitance/voltage/ESR combination.
