Molded tantalum, 3.3 µF at 25 V
The TPSB335K025R0750: This is a molded tantalum capacitor from the KYOCERA AVX TPS series, rated 3.3 µF at 25 V with ±10% tolerance. The 750 mOhm ESR is the figure that matters most for ripple current handling — a lower ESR means the cap runs cooler in a switching regulator output filter, and this value sits in the middle of the TPS range for the B case size. If your board sees 105°C ambient, this cap still has 20°C of margin before the upper limit.
The 0.138" x 0.110" footprint is standard for 3528 tantalum caps; your existing 1210 pad layout will accept it.
Sourcing and fit for your BOM
The TPS series is a general-purpose molded tantalum line, so if you need a different capacitance or voltage rating, the same case code and footprint will likely accept a sibling part without a board spin.
