3.3 µF at 10 V — TPS series molded tantalum
The TPST335K010R1500: It belongs to the TPS series, a general-purpose line for surface-mount designs where volumetric efficiency matters more than ultra-low ESR. The 1.5 Ohm ESR at 100 kHz is the figure that governs ripple current handling and self-heating — at 10 V and 3.3 µF the capacitor is sized for decoupling and bulk storage in low-to-moderate ripple applications, not for high-frequency switching supply output stages where sub-100 mOhm parts are needed.
Footprint and rework considerations
The molded case is rework-friendly: no conformal coating to burn off, and the termination pads are wide enough for a standard chisel tip iron if a hot-air station isn't handy. Pin 1 orientation is marked by the chamfered corner on the top face — easy to spot under a loupe.
Temperature range and operating environment
The molded construction handles thermal cycling without the cracking risk of some conformally-coated tantalum parts, provided the board's CTE is matched.
