22 µF, 35 V, 200 mOhm ESR — the ESR drives the filtering decision
The TPSE226K035R0200V: The 200 mOhm ESR at 100 kHz is the number that decides whether this cap handles the ripple current in a switching regulator output or a bulk decoupling bank — lower ESR means less self-heating and better high-frequency bypass. At 22 µF and 35 V, it sits in the mid-range of the TPS series, sized for circuits that need the voltage headroom without the footprint of a larger case code. The molded 2917 (7343 Metric) case with size code E matches the standard tantalum land pattern for that footprint — no special pad geometry needed. Tape & Reel packaging means it feeds straight into a pick-and-place line without a reel change.
The 2000-hour endurance at 125°C means it survives sustained high-temperature operation in a power supply or a motor drive output stage without premature capacitance loss. The ±10% tolerance is the standard precision for tantalum electrolytics — tight enough for timing circuits and filter poles where the absolute value matters, but not over-specified for bulk decoupling where the ESR and voltage rating dominate.
Active production — no lifecycle flags to watch
Listed as Active with no NRND or EOL markers — this is a current-production part that KYOCERA AVX continues to manufacture. No last-time-buy clock ticking, no successor to track. For a BOM that needs this exact capacitance, voltage, and ESR combination, it is a stable line item.
