The TPSE107K010R0125: The 125 mOhm ESR is the figure that governs ripple current handling and self-heating in the application. For a 100 µF cap on a switching regulator output, the ESR sets the output ripple voltage amplitude; a lower ESR means less ripple for the same ripple current, but also reduces the damping of the LC filter resonance.
2917 footprint — board-fit without a layout change
This footprint matches the existing pad layout used across the TPS series, so a BOM swap from a different 100 µF tantalum in the same case requires no board spin. Surface-mount assembly on a standard reflow profile with the molded epoxy body. The ±10% tolerance covers the typical production spread for tantalum electrolytics; for bulk decoupling where the exact capacitance value is not critical, this tolerance band is the norm.
Temperature range and operating environment
Rated for -55°C to +125°C, this capacitor spans the full industrial temperature envelope and the lower end of automotive ambient. The molded construction provides mechanical protection against board flex and vibration compared to conformal-coated tantalum chips, though the failure mode under reverse bias or high inrush remains the same — tantalum capacitors require voltage derating and current limiting for reliable operation.
Active lifecycle — no end-of-life signal
Tape-and-reel packaging supports high-volume pick-and-place; cut-tape option is available for prototype or low-volume builds.
