68 µF bulk decoupling in a 2917 footprint
The TPSE686K025R0125: The ±10% tolerance and -55°C to 125°C operating range cover the full industrial temperature envelope, so the capacitance stays within spec across a motor-drive cabinet or an outdoor telecom enclosure without a derating step at the high end.
The molded case (Type: Molded) and TPS series designation indicate a standard tantalum construction with a solid electrolyte and a flame-retardant epoxy encapsulation. The 125 mOhm ESR is the equivalent series resistance at 100 kHz and 25°C. The low ESR also improves the transient response — the output voltage recovers faster after a load step compared to a standard tantalum with 500 mOhm ESR.
