100 µF, 10 V, 80 mOhm ESR — what that means on the board
A lower ESR means less voltage ripple and cooler operation in a buck converter output filter or a decoupling bank for a fast-switching IC.
The molded case handles the thermal cycling without cracking — a common failure mode in conformal-coated tantalums that see wide temperature excursions.
The 2917 (7343 Metric) case measures 7.30 mm x 4.30 mm with a seated height of 3.10 mm. Manufacturer size code D. It is a surface-mount part, polarity marked on the top — the anode stripe is unmistakable, so a field swap is straightforward if you have the hot-air station or soldering iron.
KYOCERA AVX continues to manufacture the TPS series. No direct pin-compatible replacement listed; the TPS series is the current standard for this form factor and rating.
