The TPSB225M035R1500 is a molded tantalum capacitor from the KYOCERA AVX TPS series, rated 2.2 µF at 35 V with ±20% tolerance. The 1.5 Ohm ESR at 35 V means the ripple current capability is limited by self-heating — for a 35 V rail at 85°C ambient, derate the ripple current per the manufacturer's curve to stay within the power dissipation envelope of the B case.
Active production — no LTB deadline
confirms active product status. The part can be designed into new builds or replenished against existing BOM lines without a looming cut-off.
Military temperature range and package
The B case (1411 / 3528 Metric) measures 0.138" x 0.110" with a seated height of 0.083" — a common footprint that matches standard tantalum pad layouts on two-layer and four-layer boards.
