The TAJE477K010H is a Molded tantalum capacitor from the TAJ series, rated 470 µF at 10 V with ±10% tolerance. The 500 mOhm ESR at 100 kHz sets the ripple current capability — for a 470 µF bulk cap, this ESR keeps self-heating manageable in a power-supply output or point-of-load decoupling role.
In an avionics power rail or a downhole sensor module that sees 125°C ambient, the capacitance stability and leakage current remain within the datasheet limits — no derating curve guesswork.
Both are 470 µF, 10 V, ±10% tantalum capacitors, but the TPSD477K010R is from the TPS series (low-ESR) in a D case (7343-31), while TAJE477K010H is the TAJ series in an E case (7343-43). The ESR and case height differ — confirm the board clearance and ripple current requirement before substituting.
The 2917 (7343 Metric) case measures 7.30 mm x 4.30 mm with a seated height of 4.30 mm max. The E-size code footprint matches the standard 7343-43 tantalum land pattern — no via-in-pad required.
