Sizing for power rail decoupling and filtering
This TAJD475M035RNJ is a 4.7 µF molded tantalum capacitor rated at 35 V, housed in the standard 2917 (7343 Metric) surface-mount package. The ±20% tolerance and 1.5 Ohm ESR are the numbers to budget for ripple current and self-heating in a supply rail filter or bulk decoupling application. At the high end, the ESR derating curve in the datasheet governs the allowable ripple current — the 1.5 Ohm room-temperature figure rises as the case heats.
Size code D: 7.30 mm x 4.30 mm footprint with a seated height of 3.10 mm max. The 2917 (7343 Metric) land pattern is a JEDEC-standard footprint — no special fan-out or via-in-pad required for this two-terminal molded case.
