4.7 µF, 10 V, 5 Ohm ESR — the decoupling spec that matters
The TPSR475K010R5000: The 5 Ohm ESR at 100 kHz is the parameter that governs ripple current handling and self-heating in a DC-DC output filter or bulk decoupling position — a lower ESR means less voltage ripple for the same ripple current, but the 5 Ohm figure is typical for a small-case 0805 tantalum at this capacitance and voltage.
Case size and board-fit
The molded construction gives a consistent outline for pick-and-place vision systems, and the Tape & Reel packaging feeds directly into automated assembly lines. The manufacturer size code 'R' maps to the standard EIA 0805 footprint — no special pad geometry is required beyond the usual tantalum capacitor land pattern.
Temperature range and application envelope
The MnO2 cathode system is inherently stable across this band — capacitance change with temperature follows the typical tantalum characteristic (roughly ±10% over the range), so the 4.7 µF nominal value holds within tolerance across the full operating window.
Active lifecycle — no obsolescence risk
The product status is Active, meaning KYOCERA AVX continues to manufacture and support this ordering code for new designs. For BOM planning, this part can be specified without a near-term migration risk.
