Product details

ESR and the 125 °C endurance window

The TAJR475M006RNJV: At 7 Ohm ESR at 100 kHz, this 4.7 µF tantalum dissipates more ripple current than a low-ESR polymer would — the 2000-hour lifetime at 125 °C assumes the ripple current stays within the derating curve, not just the ambient temperature.

0805 (2012 Metric) case, size code R, with a seated height of 1.20 mm max — the low profile fits under a 1.5 mm clearance on a densely populated PCB, but the 2.05 mm x 1.30 mm footprint limits the copper pad area for thermal conduction, so the ripple current rating is package-constrained.

Frequently asked questions

What is the ESR of TAJR475M006RNJV?

7 Ohm at 100 kHz. That is a standard ESR for a small-case tantalum at this capacitance and voltage — expect ripple current handling around the 100-200 mA range at 100 kHz before self-heating cuts into the 125 °C lifetime.

Does TAJR475M006RNJV require voltage derating?

Industry practice for tantalum capacitors is to derate to 50-60 % of rated voltage for reliable operation. At 6.3 V rated, a 3.3 V rail is safe; a 5 V rail leaves only 1.3 V headroom, which increases the failure rate under surge or ripple conditions.

What is the closest alternative to TAJR475M006RNJV in the TAJ series?

The TAJ series includes many 4.7 µF, 6.3 V parts in different case sizes (A, B, C, D). The R case (0805) is the smallest; a B case (1206) alternative would have lower ESR and higher ripple current capability but a larger footprint. No pin-compatible issue — it is a capacitor, not an IC.
