The TPSD336M035H0300: The molded construction (type: Molded) provides consistent dimensional control and good moisture resistance for general-purpose surface-mount assembly.
Capacitance and voltage margin
33 µF at 35 V rated voltage gives solid margin for 24 V or 12 V rails — the 35 V rating absorbs typical switching transients without exceeding the derating guideline of 50% for tantalum capacitors. The ±20% tolerance is standard for tantalum electrolytics; the actual capacitance at 35 V bias will be near the low end of the range, so budget for the minimum value in timing or filter circuits.
ESR and ripple current
300 mOhm ESR at 100 kHz sets the self-heating under ripple current — for a 33 µF cap on a 100 kHz buck converter, the ripple current rating is roughly 0.6 A RMS before the internal temperature rise exceeds 10°C. The TPS series is positioned as a low-ESR line, so this ESR figure is lower than standard tantalum parts of the same case size, making it suitable for output filtering on moderate-current DC-DC converters.
