30 mOhm ESR and what it buys the rail
The TPME477M010R0030: The 30 mOhm equivalent series resistance is the headline spec that sets this cap apart from standard tantalum parts (typically 100–300 mOhm). Lower ESR means less self-heating under ripple current — a 470 µF bulk cap on a 5 A point-of-load rail dissipates roughly 0.75 W instead of 2.5 W, keeping the board temperature rise under control. Rated 10 V with 470 µF capacitance, the part fits output filtering for 3.3 V and 5 V rails where the derating margin (typically 50–80 % of rated voltage) keeps the tantalum safe from surge failure.
Active lifecycle for new designs
Listed as Active — no last-time-buy window or NRND flag. This cap can be designed into new production without an obsolescence clock running.
Temperature grade and board fit
Full -55 to +125 °C operating range qualifies the part for avionics power supplies, downhole instrumentation, and satellite bus filtering where the ambient temperature swings past the industrial -40 °C floor. 2917 (7343 Metric) case, size code E — 7.30 × 4.30 mm footprint, 4.30 mm seated height. The molded package is compatible with reflow soldering; standard PCB land pattern per the KYOCERA AVX application note for the TPM series.
