At 470 µF, that ESR keeps the ripple current capability around 1.5 A RMS at 100 kHz, which matters for output filtering on a switching regulator where the cap sees the inductor ripple directly. ## Temperature range and field-fit The molded construction handles the thermal cycling better than conformal-coated chips; the epoxy body has a CTE closer to the PCB, so the solder joints see less shear stress across the -55°C to 125°C swing. The ±20% tolerance is standard for tantalum electrolytics at this capacitance density — the derating rule of thumb is to stay at least 20% below the rated voltage for DC bias, so 4 V rated means 3.2 V max continuous in practice to keep the failure rate in the low ppm range. ## Active production and sourcing Listed as Active — the TPS series remains in KYOCERA AVX's standard catalog.
