Bulk decoupling for a 10 V rail
The TPSY157K010R0150: That ESR figure is the one that decides its ripple-handling ability in a power supply — lower ESR means less self-heating and better filtering of switching noise on a 10 V rail. It belongs to the TPS series, a general-purpose molded tantalum line from KYOCERA AVX, and carries a ±10% tolerance. The molded case gives it a consistent footprint and good mechanical stability during reflow.
Rework and board-fit realities
It reflows cleanly on a hot-air station if you preheat the board to 100 °C first; the molded body doesn't crack as readily as some conformal-coated parts under thermal shock. Surface-mount only — no through-hole equivalent in this order code.
Sourcing posture for this BOM line
It ships in tape-and-reel packaging, which is the standard for automated pick-and-place assembly.
